2. Lose the denial. The reality is that even in conservative circles, possibly even yours, there may be problems with sexual harassment and sexual assault. I grew up in a strict Catholic middle-class family. I have never had a "wild" phase and have always been cautious about what kind of men I spend time with, and I have personally known one "devout" Catholic man who committed date rape and another who attempted it and failed. It's pleasant and comforting to believe that these problems only affect those other people--promiscuous college students, people of other races or religions, poor people, whoever. This attitude is not just elitist and borderline racist, it's also dangerous and stupid.
3. Accept that men can control themselves. This means not making statements like, "If he's straight, he will make a pass at you," or "What did you expect? Men are just hardwired that way." Men have free will. If you or any man you know can choose to have self-control, so can every other man on the planet, including the one taking your daughter on a date or the one she might run into at a party. Never start a sentence, "Yes, men are responsible for their actions, but..." Chastity, the way it's currently spoken of and taught among conservative Catholics, puts most of the burden of purity on the shoulders of girls and women, an attitude which has moved seamlessly into questions of physical safety and assault.
4. Teach your sons to defend and protect others. Teaching young men to be chaste and not sexually aggressive, while necessary and commendable, is not enough. They must also keep their eyes and ears open, and speak up when their friends say or do things that are morally questionable, especially with regard to women. All women: not just their sisters or whoever they've decided is a "lady." In all Christian communities or cultures, there has been a high level of expectation from men to protect others, even total strangers. When men have a "not my problem" attitude, or are given the impression that it's prudent to stay out of harm's way, they are allowing the problems to flourish. It may be tempting to believe that keeping to yourself has a neutral effect on society as a whole, but it doesn't. There's no neutral as long as predatory people exist.
5. Teach your daughters the exact same thing. Being female is not a free pass to ignore problems. Sitting around waiting for someone else to act is not a good example of female fortitude. In the absence of any other kind of help, a woman still has to act, in whatever way is appropriate or necessary to the particular situation.
6. Don't assume church-attending religious men are worthy of trust. They might be, they probably are, but they don't automatically deserve a blind eye simply because they show up at Mass every Sunday. Men should not be offended by this. It is not a presumption of guilt, but rather the expectation that character counts and is based on each individual's chosen actions. Every Catholic girl has horror stories of Mass-attending boyfriends who pressured her for sex. I do, and I've gone out of my way to avoid men like that. It became obvious to me during those experiences that men can get away with problematic, immoral and manipulative actions while putting minimal effort into keeping up a good front simply because everyone assumed that they could do no wrong.
7. Understand that the culture we live in is in a state of emergency. It is not normal or common sense that a girl in a highschool in a first world country has to worry about getting raped at a party, even if she does something imprudent like getting drunk. Rape is not the natural result of mixing men with alcohol, and everyone needs to stop talking about it like it is. If a woman has to alter her behavior for her own safety, it should be made clear that this is not the norm and it is only necessary because of a pathological unwillingness to deal with a real and present problem of safety among "normal" people.
8. Do more than just tell women to stand up for themselves. Your daughter/sister/friend/cousin, whatever her age, should be able to say to a man, "If my dad/brother/friend/cousin knew what you just said to me, or tried, or asked for, you would be lying on the pavement with a broken jaw." It will do her very little good to say this if she knows, at the back of her mind, that you're too frightened of other men's opinions to speak up when something is wrong. If a woman, of whatever age, has no family or close male friends that she can turn to for this kind of support, see item #1.
9. Stop the femininity training. This doesn't mean discouraging girls from showing their own natural femininity, but it does mean Catholics must stop telling girls, in whatever subtle or underhanded way, that being a "lady" means putting on an act of always-gentle compliance and cheerfulness, and that any opinion has to be trussed up in a pink dress and high heels. Stop telling girls to hide their brains and show their ankles. The reason why this femininity training creates problems is because it is nearly impossible to unlearn compliant, male-ego-pleasing behavior in a moment of crisis. Saying "no" takes a certain amount of practice, and it's hard to get that practice if you're punished socially for saying anything that will make men uncomfortable or unhappy. Stop teaching young men that this is what "real" women are like, and stop tolerating this expectation in adult males.
10. Lose the embarrassment. Talking about rape, sexual harassment, domestic violence or any issue related to the personal safety of vulnerable people is not tacky and rude just because it makes you feel awkward. If it's not possible to discuss these issues without someone having a "well-I-never" moment, then it's not surprising that the victims of these crimes are unwilling to ask for help. Don't ask, "Why didn't she tell anyone?" if you have ever said something along the lines of "Such a thing would never occur outside of a Chicago ghetto."
11. Have a zero tolerance policy towards conservative misogyny. Rants against "evil feminists" will sound to a young girl like rants against all women. They will sound to a grown woman like they are coming from an environment that is hostile towards women speaking up against mistreatment, and that her dissenting or controversial opinion will not be treated with respect or charity. This is true regardless of your personal views on feminism, or whether you are the one making these statements or just standing by. It's true even if the men saying them are clueless, immature, or secretly mean well. If you, personally, do not speak up and make it clear that rough or aggressive language about women or towards women, regardless of their political affiliations, is always unacceptable in your presence, you are contributing to a hostile environment for women, which no one should have to put with just so you can keep your neocon friends.
12. Stop keeping secrets. If a man speaks about women in a denigrating or lewd way, tell everyone about it. If you see evidence of abuse in another family, talk about it, ask, make waves. If you're being pressured to have sex by someone you're dating, make that person a laughing stock. If you hear screaming, call the police. The likelihood of an innocent person being punished for something they didn't do is far less likely than people with something to hide would have you believe. Communities keep tabs on each other for mutual protection. Name names. It's necessary. It is criminal to protect the reputation of a criminal.
