You know, I don't have any issues at all with their personal choice to define themselves according to their interpretation of religious dogma. I am for self-definition, even if the definition we choose is one that abdicates this responsibility / freedom to some religious insititution or fantasy of god.
The only thing that gets on my tits about them is that they have chosen not to just leave it at that. Their interpretation of religious dogma, by which they've chosen to define themselves, demands that they advocate anti-gay bigotry and teach their daughters that all those other women who have struggled for a better life for all women are an abomination in the eyes of God. It smacks of hypocrisy, and I despise hypocrisy. If they are going to disparage feminism and teach their daughters it is wrong, IMO they are ethically obliged to relinquish all the rights they enjoy because of it: voting, owning property, choosing their own husbands, working for a living wage, and protection from sexual harassment and domestic violence.
