There's a difference between not showering someone with respect and positivity for having a decent opinion, and telling them to stfu.

If a man has a good opinion about feminism, I'm not going to tell him to shut up just because he's a man. I'll think "that's cool" and move on. I'm not going to put him on a pedestal because he's a man, but I won't shut him down completely either. I think it's just fucking shitty to do that.
