Wikipedia has about 400 racial/ethnic slurs against many races including white people.  I take this as evidence that racism exists in America against white people which is not just my imagination.  In today's climate, I am sure if more than 10 people read this at least half of them will tell me I don't have the right to mention such things, much less discuss them.   However, I am old-fashioned and think all things should be discussed so that we can learn from all points of view.   Further, I am still a believer in freedom of speech even if it makes you the reader, uncomfortable to unhappy.
