Gawd. The whole thing is petty & dim. It's really a small thing, like women covering their breasts (actually their nipples) in public in our culture. When it comes to things that really matter, like women's dominion over their own bodies, the double standard becomes obvious. Well, to anybody capable of seeing it. That's not rabid pro lifers going on about head scarves.
I'm not a pro lifer and yet I see your argument as "it's okay because it's just a little sexism, we only need worry about big sexism". This is not on the level of genital mutilation, but it's still bad and sexist. You can agree on that and still say TH is being inconsistent in his beliefs.
