I didn't find his comments on other races offensive, at all. Some are actually somewhat humorous. He did, in fact, spend a large part of his time summarizing the crime and imprisonment rates of black men.
The man was a devout Christian and spoke on the teachings of the Bible, which he held as Truth. Unfortunately, his view on homosexuality will not sit well with some, but that doesn't make it wrong.
My guess is that he did more good for the underserved and underclassed citizens of our country than 99.9% of the population will ever do.
RIP, Reggie. Can't wait to meet you one day.
