1. Feminists are rude
Only to utter fuckheads that deserve it.
2. They tend to be rich or upper middle class
Just going to point and laugh at you there.
3. They over-analyze everything which men do. So now a man cannot even open his mouth to pass a little comment or say something ordinary without thinking twice or thrice how his feminist-influenced wife will scream "misogynist" and create an argument out of nothing.
Only if what the man has said is misogynist. If he's commenting about the weather I usually let him speak. If he turned round and told me that feminists are rich, rude, stupid and only in it for the power, then he'd get a different response.
4. Feminists want political power
Yes, sorry, man, but power sharing is what we're after. I know that's going to be difficult for you to understand, but political power is how things are changed. And things need to change, for everyone's sake.
5. most feminists are cynical
The opposite of optimist is pessimist, not cynical. You might need to get a dictionary.
Feel free to come back when you feel you can construct a cogent argument. Until then, I pity your poor wife, but, as she's in the US with you, there's not much I can do to help her.
