Ok, I'll tell you why I'd vote that one down (if I haven't already):
It's because the thread title says that Michelle Obama has hated America for 40 years, and I find that hyperbolic to the point of being dishonest. I prefer less partisan political threads and would want to avoid the ones that are just about tarring and feathering.
I thought people were misreading homophobia into your Homosexual Role Models thread and thought it was a more thoughtful attempt at discussion and voted it up.
I'd vote on those, based on what I see as very different substance (to me, of course) and it's not you or your politics that will influence it.
