I don't think Harry said "gayhawks," I think it was the obvious KU+Jayhawks slip combo. What I think is truly sickening is droves of KU fans using this as a rallying cry to oust Harry, who they hate, out of his profession. Obv. I'm assuming, but I don't believe that a majority of the KU mob is really too worried about effects of similar slurs on homosexuals. They're just using it as a means to an end.
This isn't something that is unique to KU though, I would imagine many groups would be doing the same thing in their shoes. It's something that bothers me a lot in today's social, political, etc. climate. People don't seem to generally give a rat's ass about an issue itself, but they'll sure as hell latch on to something if it furthers their own agenda.
