Now I don't know much about Crowder.
Actually all I know about him is the articles about him and Youtube. But I will, as the saying goes, fight for right to say it. As Apple is mis-using the copyright claim to hide an embarrassing moment, youtube uses "hate speech" to shut down various groups it doesn't like, while leaving up anti-white and anti-Semitic groups.
As someone who grew up in the Civil Rights era, I can think of any number of black leaders who would have been shut down. May I suggest Malcom X to start with.
