BS! You only have a couple examples to point out for a reason. I have given 3 times the amount your one racist has. I know or know of many others that are doing more than me and they are not racist or haters in any way.
Here's a test you liar. Sign up to a Ron Paul meetup group or yahoo group. Post some crap about how you love Ron Paul for some racist reason. See how quickly you get runoff.
