If a man starts being a sexist pos to you and ur weren't expecting to have to argue for ur right to freely exist in the world as a human being unshackled to the structures of male supremacy so early at 3 AM in the morning, don't engage with what he's saying. Don't take the bait to argue. Ur not obligated to play the feminist they so desperately want to publically humiliate into submission in order to get a dopamine hit.
Ur a human being entitled to the same rights as any other on God's Green Earth as the big man Himself intended. You don't don't owe anyone an explanation for why this has to be the case regardless of how bitter they are about it. It's their business, not yours.
So instead just address them like you're addressing a hypothetical crowd of women and he's a crazy person having a manic episode in public.
Example
"Women lack accountability
Ladies, settle down. A member of the sex most likely to abandon their kids and owes billions in unpaid child support is here to teach about accountability.
"something something Women Suck Men Better poor me I have to pretend I like them in order to date them"
Ladies, imagine giving birth to this after carrying it in your body for 9 months. Like Im so serious. Imagine calling that thing your son 💀"
(OK this is the last one I promise)
"Tirade against abortion, tattoos, or women's right to vote"
Ladies, it's important to remember that the internet is the place for men to say shit that they're too much of a little bitch to say in the public sphere at the risk of getting pounded by a pulp by men who actually do love and respect their wives/girlfriends/sisters/mothers who happen to be stronger than their wimpy arses
Just make it clear you refuse to dignify them with the response they so desperately crave in cheeky but fundamentally non-threatening way, honestly. That should do the trick.
Stonewall them.
"Give me an account then so we can see if I have abilities."
"If men are better, why are you the ones in a loneliness epidemic?"
"I also don't like men with tattoos, nor do I think men should have a say in abortions, nor should they be allowed to vote!...Oh nobody cares what I think? Hm...Who cares what you think, then?"
kick them on their nuts
