I believe that feminism is a broad church (I have occasionally joked it is a broad's church) and that almost any political, religious or world view is compatible with feminism, except a belief in restricting reproductive rights for women. That, to me, given that it hands agency over a woman's body to others, is a bridge too far. It’s the equivalent of saying you are a Christian but don't believe in God.

But, apart from that proviso, in the spirit of the more the merrier, I will cheerfully accept anyone who claims to be a feminist as a feminist.
