Notice how much actual common sense 'commonsense' has! When confronted with facts, he excuses himself instead of moving an inch off his stance.
I laugh anytime someone on the left cries crocodile tears about racism while doing every single thing that they can think to do to keep race alive and well as an issue in this society. They simply cannot do the one thing that would end racism and that is to stop pointing out everyone's race. If it is treated as a non-issue, it will become a non-issue, as was in fact happening in full view of everyone in this country until Barack Obama showed up to stir the pot and get racism back on the hot list of social topics.
The only solution to racism is to stop talking about people's race. It is the ONLY solution and it WILL work, which is why the left will never stop talking about it.
