Standing up for women’s rights doesn’t necessarily equal creep - that’s what men should be doing. But you’re not wrong that men who are overly vocal about saying they’re a feminist are often creeps. It’s kind of like the Nice Guy thing in my experience - if you have to tell me (ad nauseum) how nice you are, I’m definitely suspicious. Men who are actually feminists don’t usually feel the need to say it 30 times in their dating profile, they’re just out there living it and it’ll be obvious to anyone paying attention.
