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

[Dystopia]

That's a very brief description, but it's possible to create a broader spectrum definition that encompasses many others traits... Let me give you my example - I'm a gnostic atheist and I'm not as heavily represented because I make the positive claim that god doesn't exist and because of that I happily discuss and debate with atheists regarding the definition - My definition isn't that atheism is simply a lack of belief in gods but rather either a lack of belief in any particular god or the positive claim/belief that god doesn't exist - As you can see, there is disagreement in the atheist community, I just disagreed with you. As for feminism, it is defined as a movement that focuses primary on women's rights to attain gender equality, not female superiority or male oppression. Other definitions can be forwarded by dumb feminazi groups but they are not as valid and they twist the real, most significant meaning feminism has as being a part of an egalitarian philosophy and ideology - I'm like you, and egalitarian, and that position encompasses feminism, I cannot be an egalitarian without supporting social, economically and morally fair feminist causes.

I stand by the position I've already disclosed - That people are afraid of the stigma associated with the word and that's why everyone prefers the label egalitarian or any other word/expression that works as a synonym, but that doesn't erase the fact that those people are not identifying with an ideology (gender equality) that they support.
