Yeah, because we're the ones who worship at the altar of an alcoholic bigot.
Many basketball teams in the South did not have black players on their rosters or admit black students into their institutions. The Southeastern Conference especially had many member schools so opposed to integration that some schools refused to compete against other schools with black players. Mississippi State at one time had to sneak out of town under the cover of darkness to play in the NCAA Tournament. (This, after ignoring bids in earlier years.)
During that time, Rupp was playing all comers around the country, white or black. He often took his team to Chicago or New York to play against some of the powerhouse collegiate teams with black players. He recruited black players (at least fifteen - Lexington Herald Leader, March 31, 1990.), including Wes Unseld, Butch Beard and Jim McDaniels, but it was a difficult undertaking to convince a black player to come to Kentucky. Doing so, he would be the focal point in college basketball, as at that time Kentucky was the premier basketball dynasty. A black player would be subjected to the worst taunts and slurs imaginable during road games at places such as Oxford and Starkville Mississippi, Athens Georgia, Baton Rouge Louisiana etc. (Not to mention the aspect of arranging lodging and meals in the segregated South.) Nevertheless, there were a number of people who claimed that Rupp did not recruit these players or when he did, Rupp didn't recruit them hard enough.
When Rupp finally did sign Tom Payne in 1969, Kentucky was one of the early SEC schools (starting with Vanderbilt with Perry Wallace, followed by Auburn with Henry Harris, Alabama with Wendell Hudson) to sign a black player (*). Football players Darryl Bishop and Elmore Stephens joined the UK team in the 1971-72 season for a short time, Rupp's last season as coach. (by John McGill, Lexington Herald Leader, "Kentucky a Leader in Integrating SEC Sports," March 31, 1990.)
It is difficult to assess the attitude of a man who is long since dead, especially the Baron who was only well known by those few close to him. A large amount of anecdotal evidence suggests that Rupp showed few signs of being racist and in fact supported blacks while a few specific quotes attributed to him suggest he was indeed racist. So was Rupp racist or not ? The information at hand is too contradictory to say for certain. Most likely he was to an extent, just as the majority of white men his age living in the South at the time would be judged racist by today's standards. There are two explicit instances where Rupp, while angry, made derogatory comments about blacks to people in confidence. Was he overtly racist ? The evidence does not show any public statements or acts to suggest so.
"To put 1997 standards on Coach Rupp during the time that he coached -- in the 1930s, 40s, 50s, 60s and a couple of years in the 70s -- is totally unfair." - C.M. Newton, CNNSI, "New Era in Lexington," October 30, 1997.
"I know there have been a lot of people who thought he was a racist. But I think the times can dictate how people act -- where you're brought up, how you're brought up. If he was a racist, he wasn't alone in this country. I'm never going to judge anybody. . . . That's a long time ago, too . . . You learn from the past, and you go on." - Orlando "Tubby" Smith, Chicago Tribune, "New Face Leads Kentucky These Days," November 30, 1997.
