Brother told me feminism is cancer

Today I received an unprovoked email from my brother addressed to my sister and me and sent to the whole family where he declares he is cutting all ties with us because we are “infected by the cancer that is feminism” and “hate every male [we] meet.” I am happily married to a man and the majority of my friends happen to be (feminist) men. He goes on to blame our feminist behavior on our parents for having raised “bad kids.”

The saddest part: my brother has two young daughters.
