Agree, but if there was a racism test given to a large sample of people - I'd wager heavily that whites would be the lowest percentage. Such a test would probably be deemed racist itself so the results would not be reliable.
I once caught a guy going through our dumpster after hours and making a mess in the parking lot. I am white, he was not. I politely told him to leave. He told me that he didn't need my permission to go through garbage (on my property) and then he called me a racist. I challenged him on the racist comment and he gave me an earful on why I was a racist. Never met him before that moment.
