There is a HUGE difference beteween accepting the endorsement of some crackpot and dragging your children to a church run by a crackpot. If Obama didn't have kids, I would write off his membership in that church as something he did to gain 'street cred' in his neighborhood. But exposing impressionable children to such rhetoric is a whole other ballgame. There is also a huge difference between being affiliated with a crackpot in your early 20's and being affiliated with a crackpot in your 30's and 40's.
