Why so many "anti-feminists" in the atheist community?

[Dystopia]

What I wanted to point out, feminism is similar to atheism. I also can be of any breed and color.

That's what I'M saying. Feminism can mean whatever a self-declared feminist wants it to mean. And an anti-feminist can define it however he wants, too. So to answer the OP, we should look at how the people in question, the atheist "anti-feminists," define the word-- and at the kind of feminists they've come into contact with against whom they've positioned themselves.

It's not like that, just like atheism doesn't mean everything we want it to mean (for example it doesn't mean believing in god), you really need to inform yourself better, you're making definitions entirely subject - Using that point of view, I could as well say I'm anti-LGBT because there might be some gay people who hate straight people, but would that justify it?

Definitions are supposed to explain what something and isn't, they're not subjective, if I used your argument to self-define in the exam I'm gonna' have tomorrow I'd probably fail after answering the first question.

EDIT - So by your logic everytime someone self proclaims a definition of something we'd have to accept it as valid - For example I'm going to proclaim I believe in animal rights and that to be an atheist you need to desbelieve god and support animal rights - By your logic only, the community has to accept my definition as valid since I'm self proclaiming it, even if I'm only one person
