Truly, this is one of the most curious letters I've ever read in the RG.  Is Bettman serious?
Just what does Bettman think he "learned from Wallace?"  
In the early 60s George   Wallace was one of the most  extreme of all the southern racist politicians and  one of the strongest foes of racial equality. 
As well as Duke, he later spoke at the UO, in Mac Court.  As I recall the place was packed with students who laughed hilariously at Wallace's inane statements, such as (I paraphrase) "If any of them pointyheaded bureaucrats lie down in front of my car by God I'll just drive right over them!"
The best thing that can be said about Wallace is that he eventually came to his senses (after he was shot) and spent his final years trying to make up for the pain he'd caused with his ignorant political racism.
Later, of course  Communist leader Gus Hall spoke at Hayward Field and like Wallace his absurd rhetoric was greeted with laughter.
Ann Coulter deserves the same response at Cal.
