Freedom of expression so go for it. The issue is that the Joke is Obama is a slave and must pick cotton, ha ha because he is black or half black as the case may be. The trouble is he is living in the White House and would symbolized that he is now the plantation owner and maybe white people would be picking his crops in 2011, progress and change for sure. For that reason watermelon is funnier but Obama isn’t really black. He is an elitist nerd that caves to pressure. He promised change and he did the same things Bush did, he got us into a new war, he cut taxes or extended tax cuts, and so on. This is what I mean that race jokes are lost on him, it doesn’t make sense any more.
