Of course it wasn’t racist to call Bush a chimp.
Only a racist thinks the different races should be treated the same...
I agree with you about the similarity. You have a good point. On the other hand, I don't know if anyone with an official political position got caught comparing Bush to a chimp. Usually, it was just a bunch of jerk-offs who didn't have a position to resign from. It's really not a smart thing to do for a person who has political ambitions or power.
