I’ve said it before.
Only a racist will use the racist argument to prove they are not racist.
Which is not only true, but devastating. Some of the most harmfully racist people you'll meet are liberals hell bent on proving how enlightened they are. They'll be the first to champion and vote for causes that guarentee misery and poverty for non-whites, so long as the stated rational for the program sounds nice.
It's not the effect they care about, it's the process. So long as they feel good about proving themselves and their moral superiority, they'll never change.
