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

[Edwardo Piet]

Then you agree with Catholics that Protestants aren't true Christians, for instance?

No... I don't know what gave you that idea? The definition of Christian doesn't exclude Protestantism, Protestantism is a subset of Christianity. The fact Catholics think otherwise doesn't make them right.

I was merely pointing out that the NTS fallacy is commonly misunderstood and used incorrectly, so I provided you with the correct definition. I used to misuse it too.

Myself, I think the definition of "feminist" is muddled enough that winnowing the wheat from the chaff is a fool's quest. Rather thaan deal with how a person labels themselves, I prefer to deal with the individual. If someone calls themselves feminist and then goes on to spout nonstandard rhetoric, I'll address the rhetoric without worrying about the label.

I drew an analogy between atheism and feminism to explain how different groups of feminists don't define feminism itself just as different groups of atheists don't define atheism itself. True, as language develops bastardized definitions also become official definitions sometimes, but then in that case let's not equivocate the different definitions of the same thing.

The primary definition of feminism at the very least = Pro-women's rights and if there really is a bastardized version of feminism that has become an official definition in the dictionary, then let's recognize when the equivocation fallacy is made and people conflate the two.

Either way, different groups of feminists don't define feminism just as different groups of atheists don't define atheism. The dictionary defines feminism and atheism. If a group of atheists get together who think all religious people should be killed they don't define atheism itself at all. They're just a group of murderous people who happen to be atheists. Same thing would apply to a bunch of feminists who got together thinking all men should be killed. They don't define feminism. And feminists who also happen to be anti-men don't define feminism just as atheists who also happen to be anti-theists don't define atheism.

From the dictionary: "the advocacy of women's rights on the ground of the equality of the sexes."

I don't care how many feminist groups there are that get together who are also anti-men, they don't define feminism itself. The above definition defines feminism.
