You don't have to work on that, but you do have to work on yourself. What you said is an example of internalised misogyny, and it is part of the problem.
I'm very sorry for the actions of some men, but neither of us can control that. What we can control is how we react to it.
It's not the fact that you're saying men should change; it's the fact that you're generalising.
By saying that all men are evil, you're letting individual men off the hook, and you're perpetuating the very problem you claim to be fighting against.
No one should have to prove they're an exception to a hateful statement.
I understand and validate your feelings, which is why I care so much about telling you about the misogyny you've internalised.
I don't see you as a prejudiced bitch; I see someone who has been victimised and hurt, and who has turned that hurt into something that will harm you and other women.
I understand it's exhausting, and I don't mean to attack. I just want to see you heal. Don't you think this has taken enough from you?
