I have seen here a few times, and just heard it on cspan, people are trying to push the 'there is no racism' line. So I think it is really worth understanding what is going on with the white racist propaganda at the moment. It is low hanging fruit for the people that would see harm to our society.
America has been very quick to send the law at minority communities, but much slower to deal with the white communities because of our historic power structure. And with online trolling going towards 'racism is not real' they are trying to make it ok to dehumanize people, which is very scary.
