So, oORaidROo, there are a few things we need to clear up...
Racist and Right-Wing are not necessarily the same thing. There are many racist Democrats. I am a conservative-minded individual (right-wing to some people) but an definitely not a racist.
Joe Wilson is also not a racist just because he called Obama a liar. I guess your memory is a little short. I remember much hate speech against pres Bush calling him a liar. You know "Bush lied, people died". It's not an impossibility for a politician to lie from time to time. Actually, they're probably lying more than they're telling the truth, Dems and Repubs alike.
As for the Obama, Hitler pics... they certainly not racist since Hitler was white but are more political suggesting that Obama is a dictator. The questions about Obama's birth are legitimate. If he wasn't in fact born in the U.S then he's not eligible to be President. He still hasn't proven his birthplace by the way.
Now, as for the picture... I think it's stupid and not really even funny. However, not really worth a bunch of controversy in my opinion.
