To a white man, who is a friend... a good friend, who generally agrees on most things, but puts his foot down when I or his wife talk about feminism in the most pleasant of ways, and claims that being a Secular humanist is better and feminism is bad?

Humanism seems like a great concept if we were all equal already. It seems like an appealing cause especially if you are already on top(i.s white male). How do I teach him?
