Well, when you teach little boys that "it's never okay to hit a woman", you are also teaching them to not defend themselves. And also when you try to say that we should always trust women, you're teaching men that they can't defend themselves or risk going to jail for self-defence (which the woman would spin as assault)
Are you daft? This is exactly what they've been telling women. And there's nothing wrong with saying it to either gender. I'm pro choice but if you live somewhere where abortions are illegal, the only method to avoiding a pregnancy 100% of the time is to not have sex. Grow up.
