@cicerone imposter,
Sorry, wrong argument. Gays and lesbians and all butt riders and rug munchers are a behavioral driven group - not a true minority. I would guess that most members of the Log Cabins and Dykes on Bikes recognize this simple fact. That you don't doesn't surprise me at all.
When it comes to southern segregation, one should note that Lincoln was a Republican. Robert E Lee, George Wallace and Robert Byrd (KKK grand poobah who also pushed for Lee's pardon in the 1970's) most certainly were/are not.
