How accurate is Dave Chapelle's depiction of the KKK in his famous comedy show?

Dave Chappelle is a well-known comedian who did stand-up acts for people. He is very funny. He had his own show starting in 2003 when he got his own show called Chappelle’s Show. When this show first began, Chappelle did a skit about a man who was black and blind and he was in a white supremacy group believed to be the KKK. The skit lasted almost ten minutes.

This was a risky skit based on the content of the skit, but many people loved it due to the authenticity of the skit. Chappelle knew it might cause a stir, but not to the extent of which it did. He based some of the character on his grandfather who was blind.
