Feminists make me grumpy. (feminists in general, not friends who happen to also be feminists)
I am in favor of equal rights, for men and women (pretty much everybody, really)
In fact, I am very firmly and strongly in favor of equal rights and fair treatment for everybody. But as far as I can tell, Feminsm is not about equal rights or fair treatment. It's about "girls are great because boys are so stinky" and about some weird sort of turning the tables to objectify/belittle men. That I'm not in favor of. Any more than I'm in favor of belittleing women.
It seems to me that if something is out of balance in the way people are treated, the answer is not to swing everything too far the other direction, but to balance it.
Also, there really are biological differences between men and women. I heard a feminist writer decrying the inherent unfairness of annual pap smears for women, but not men. men just can't get cervical cancer. Try as you might, it just won't happen.
To be perfectly clear -- I am in favor of equal treatment for everybody. Health plans that cover Viagra, but not Mamograms? That's not right, and I'm against it.
Maybe I'm wrong about feminism in general, and only extremists make me grumpy.
