I lost respect for my Dad

One night I had a argument with my father. He claimed that white people were better than people of color just because their white. He tried to use a bible reference but I shut him down and tried to get him to see how racist and ignorant he sounded. Growing up these things kept happening with racist jokes and harmful comments about people of color and I was made fun of for defending people who weren't white. I've now learned he was in the KKK for a brief time and we don't speak. Not all of this is due to our differences when it comes to how we view race but I just can't see him as a good person anymore.
