When people look for racism they find it.  This is true.  Every time it has been studied in a systematic, scientific way racism has been found.  Read a book.  It's a big problem and sweeping it under the rug with platitudes doesn't help.  Employers are more likely to call a white person with a criminal record back for another interview than blacks with no criminal record.  Other experiments have revealed that simply having a black sounding name vs a white sounding name on fictitious, identical  resumes results in fewer job offers.  Black children are subjected to punishment more often and more severe punishments than their white counterparts.  Note: I am talking about experiments where all other factors are carefully controlled, although there is plenty of real-world evidence that blacks are treated unjustly.  I haven't read any studies about racism against Natives but would love to see one.
