No, I think the reply is appropriate enough. The comment you quoted is an extremely mysogynist take, falling right into the incel perspective of "if women refuse to have sex with men, they are inconsiderate."

The value of women is not just for men to have sex with them—they have the agency to decide for themselves what they want to do with their own bodies. This is basically what the downvoted post is saying. Women choosing not to put out doesn't "radicalize" incels any more than women showing a bit of skin creates rapists.

If there are men who can't get over the fact that some women might choose not to have sex with them for political reasons, they can read Lysistrata or something.

I'm kinda tired of arguments that expect the minoritized group to not "radicalize" the majority group. Why is it on the people who are being oppressed to not offend people aren't even necessarily oppressors? Honestly, this comment is tone deaf as fuck.

I actually think the movement is a bad idea, but for another reason. I just think it's unreasonable to ask people to avoid relationships. The male dating pool is totally fucked for girls, but if you have desires, they shouldn't be denied. Even as a bi gal who generally prefers girls and isn't looking to date guys, I won't rule out men. The vast majority are undatable, but that's because so many of them aren't raised right. They aren't taught proper empathy and respect for others, never having a chance at being good partners. It's a systemic problem, only further reinforced by the internet and toxic male culture.

They aren't taught that they NEED to constantly earn women's trust and love. They aren't taught that kindness AND strength are what women generally look for. Be a fucking hero who fights for his loved ones. Make her feel safe, not in danger if she doesn't "pay up." Be ambitious AND kind.

IMO the context does absolutely make up for it

It really doesn't, since the comment you quoted is basically saying that women making decisions over their own bodies is the cause of misogyny, which is the most generic MRA victim blaming bullshit which doesn't deserve to be legitimised by being seriously addressed, nor defended by people pretending to have good faith.

Yikes. The context does not help.
