A Republican Race-Betrayer is the very rare Phenomenon in which a Black or Hispanic man or woman chooses to be a Republican over being a Democrat or independent. 95% of the time Republican's are White-Christian males and females with a very limited understanding for anyone who is Non-White or Non-Christian. So anyone that comes from a Non-White ethnic background, who chooses to be a Republican, is often times viewed by persons from their own culture as being a Race-Betrayer. The Republican party was started in the mid 1800's, where slavery was a common practice. This does not imply that all Republican's are racist. But current out spoken Republican's like Rush Limbaugh, Bill O'Reilly, and Ann Coulter; have done little to dispel the idea of conservatives being only for the support of White-Christian's, instead of an "ALL PEOPLE'S" acceptance model. As America has grown to include people from all different races and belief systems, the Republican party has remained almost unchanged in their views of others. This in the face that Caucasians are becoming less of the majority and more of the minority race in America. So Race-Betrayers, especially is predominantly Non-White areas of the USA, are viewed in a very negative light. The support of a political party, while not always looked at as being relevant to true change, is still viewed as the only way to bring about change. So the support of a political party like the Republican's, that have a very ify record of including people from all walks-of-life, by those very people who are NOT included in it, are then by all accounts a Race-Betrayer.
I could live to be a 1000 years old and still not understand the mindset of Republican Race-Betrayers. A Black man supporting the Republican party is like PETA supporting the National Cattlemen's Beef Association. It's doesn't further any of that person's human rights.
