You are clearly regurgitating partisan talking points. This is not a fact, this is a particular framing of a particular issue straight out of some far-right blog. Your feigned ignorance ("I have been doing a lot of research lately and I was shocked to find out that the Democrats are the party of racism") isn't convincing to me. You are either extremely ignorant and naive of American history, and consequently, are swallowing propaganda hook, line, and sinker, or you are dishonestly disseminating propaganda.
It is a well-known established fact that Republicans judge people by their character and ability, not skin color. The left sees race everywhere. They would rather a company hire an unqualified black man over a qualified white man just so they could fill their diversity quota. This is so disgustingly racist I can't even believe people buy into it. Republicans have no problem with black people getting the job, as long as they are the BEST QUALIFIED for it. If I go in for surgery and I find out my surgeon only got the job because of his skin color and not because of his ability, I'd be downright terrified for my life.
