Why is America racist towards blacks but tolerant of filthy racist eastern european immigrants?

Many African Americans are hardworking and have been in this country for generations, yet white americans treat us like trash. They fill the media with disgusting stereotypes about us and treat us like animals, yet they are totally accepting of Eastern European immigrants with no potential just because they are white. Most of these immigrants are illiterate, filthy and racist. Many of them hate blacks more than white americans, yet they are accepted by white america even though they just got off the boat from a communist hell hole. Why is this, white america should be ashamed of itself. You treat blacks like crap,but accept filth from other countries. This is more of a reason for an all black state, so filthy whites can't discriminate
