I won't post the Tweets here because not only do they break TOS, they are extremely offensive. And yet, this is what the anti-Obama crowd spews. I won't say that they are Romney supporters because I don't know that for a fact. I think that they are just hate-filled, fearful, no-brains who have found an outlet that lets them say whatever they want without any consequences. See the above link if you want to subject yourself to them.
Still, it does show the undercurrent of prejudice & bigotry in our country...not just against people of color (any ethnicity) but also against orientation & women. It makes me so sad that we, as a country, haven't moved beyond this. It's truly pathetic.
