One of the big controversies about Dallas CC & Brook Hollow is they recieve property tax exemptions, which means residents, black & white, are being forced to subsidize the behavior.
I think Kansas City admitted at least one minority member in response to publicity over Tom Watson quitting. I think Shoal Creek & Augusta Natl. did the same after the PGA instituted a rule not to hold tournaments at segregated clubs. The PGA instituted the rule after getting a lot of bad press for holding tournaments at segregated clubs. I guess they weren't going to let a little racism stand in the way of making money.
