In reality nothing it is the old Nazi final solution just wrapped in it's new 21st century proper wrapping. See the KKK, Neo Nazi's etc... have learned how to get more supporters. They don't wear the hoods, shave their heads, or walk around in Nazi uniforms they look like Ward Cleaver down the street. They wear suits and look professional all the while subtly passing on their bile and hatred in nice ways to make racists not seem like racists.
