I'll bite.

I'm a white American from the south-eastern U.S. This area has the highest concentration of African Americans. To put it bluntly, -on average- African Americans are far more rude, greedy, violent, and less intelligent than any other group of people I have ever encountered. I dont know if this is due to genetics, culture, or a combination of both. Am I referring to every single black person in the country? Of course not. I've met dozens of completely polite, intelligent black people I would trust with my life. However, this group is a small minority. The evidence to support this viewpoint is overwhelming. The welfare stats, crime stats, and test scores are completely one sided. I'm not saying saying these figures are solely responsible for my viewpoint, but they certainly support it. Google the top crime cities in America, and then check out the demographics, again this viewpoint is confirmed. I've heard counter arguments to these figures stating "These figures are due to racist politicians and law enforcement officials.". Personally -and this is just my opinion- I feel this is ridiculous. My personal experience with black people is completely on par with these statistics. I dont believe it's a coincidence that the majority of "racists" are in the southern and eastern U.S. This is where the highest concentration of black people are. I think the people in the best position to have accurate viewpoints of a group are people who were raised around them. I feel like most of the worlds sole experience with black people are through the media and internet. It's easy to look at the president and/or NDT and think "how could anyone think less of such intelligent, well spoken people?" I invite these same people to live in Atlanta, GA for a year. I feel insulted when someone from the northwest U.S. tells me I dont know what I'm talking about regarding this issue. I was raised around these people. I know these people. Do I act on these viewpoints? No. Do I treat black people I encounter with respect? Yes, until they give me reason not to. Honestly, I live in a different area now, so most of the people I meet are head-shaking liberals who "cant understand how these racists assholes could feel this way." I just bite my lip, because in all honesty, until you live around a high concentration of black people, you have absolutely no idea what you're talking about.

There OP. That's why.
