making money off racism

First, there was the sock monkey dressed in a suit that was marketed as resembling Obama.

Well, actually before that there was the Curious George t-shirt.
Now there is another...and third.

But now there are buttons that Texas Republican Party Convention goers can buy.

Either these people who make/sell these items are too ignorant to get that this is deeply offensive, or they see another chance to make a buck off racists. Last time I checked though, I didn't hear anything about these folks contemplating donating the profits to the NAACP or anything like that.
