Let's not applaud ANY feminism. Would you applaud a chauvinist for being a chauvinist? No, you wouldn't. Do not accept sexism from anyone. I do not consider recognizing a biological and quantifiable difference as sexist.
Next time you read the word feminist, think chauvinist and see if you feel differently... I'm sure you will.
Now, if someone said "respect the author, despite being sexist", I'd support that.
