I think it's a good reminder that one of Hitler's closest "friends" and instrumental in the rise to power of the nazi party, was executed in the night of the Long knives. Ernst Rohm was publicly known to be gay. Due to this close relationship with Hitler, they determined it would weaken Hitler's image.
Copeland certainly won't be the last GOP casualty due to their bigoted policies.
Well, the fact that he was gay is perhaps a sidenote to the internal power struggle in the nazi Party, and the struggle between the SA and the SS. Hitler stayed in power by playing the people beneath him against each other, and Himmler was particularly ruthless in this regard to the very end of WW2.
