A Young Liberal has gotten himself into a spot of bother by referring to President Obama as a monkey on twitter. Now, I regard such comments as completely inappropriate but I do remember there was no shortage of people comparing President Bush to a chimpanzee. I'm unaware anyone ever got reprimanded for doing so.
President Obama is entitled to the same level of insults as any other President. To spare him such insults because of his color amounts to racism. If Bush could put up with it so can Obama.
