I don't feel bad for simps, I feel ashamed for women treating men that way
Do you criticize women who date simps?
Yes, I dislike them very much and I think they deserve better.
You shouldn't judge other people for doing things that isn't causing harm to someone else. Everyone has their own interests and preferred way of seeking romance. If what someone wants to do makes them happy and isn't harming anyone else, you shouldn't judge them.
I disagree. I think they should feel and accept the shame, I want to make them uncomfortable.
But it is not your position to decide what they want, and you definitely shouldn't be trying to make them feel uncomfortable.  This is a decision that people make for themselves, even when others disagree.  If you keep arguing, you just make yourself look bad.
