Well, there are a lot of Catholics who disagree with the blatant sexism of not ordaining women. There are those of us who reject the teaching on contraception -- teaching developed in its entirety by unmarried men, men who believe in tying up heavy burdens, hard to bear, to lie on the shoulders of others; but they themselves are unwilling to lift a finger to move them.  That's two.

Neither one is truly central to the Catholic faith.
