But you're not talking about targeting the culture that sanctions violence. You're talking about targeting the culture that sanctions violence
against the protected groups of your choice. There's a substantive difference there; the latter proposition has holes in it which I'd argue are, if not dangerous, then at least compromising to the goal of reducing violence, period.
I'll grant that not getting beaten up for being gay would've fetched me fewer beatings, and fewer would've been better than more. But no matter how thoroughly you manage to instill "don't beat up people because they're gay", fewer beatings is all you'll ever achieve by it. Considering that, if your movement has the power to succeed at the "don't beat up people because they're gay" social engineering project, it also has the power to succeed at the "don't beat up people, period" social engineering project, aiming for a lesser goal than you can attain seems to me a bit crass. (As it happens, I don't think your movement has the power to succeed at either project, so for me the question is academic. But you think otherwise, so, for you, I should think it'd be a matter of some import.)
