I would like to summarize my comments with a brief quote by Margaret Atwood.
Why do men feel threatened by men?I asked a male friend of mine.
They are afraid women will laugh at them, he said,undercut their world view.
Then I asked some women students,Why do women feel threatened by men?
They are afraid of being killed, they said.
