"I can't be racist - I know some black people. I hang out with black people. See, I'm obviously not racist".
See to me this sounds exactly what liberals say a lot.
"I don't like Obama"
"Well you're a racist"
"I'm not a racist"
"You are, prove you're not"
"Hard to prove you're not a racist, but I hang around black people, I live around them. I'm friends with black people. Maybe I've even dated or married black people"
{insert your mocking statement here}
So basically it's just an unfalsifiable thing. Nothing JBSP will do can ever disprove he's a racist.
You're displaying the same idiocy as the left. So stop doing that.
