Read a book called “The Hidden Hitler”. It makes a pretty persuasive case that Hitler (and the core leadership of the SA) was homosexual. There was supposedly a Vienna police file on Hitler in his young “Bohemian artist” days regarding his activity as a male prostitute. The file of course has disappeared.
Hitler had Roehm killed and the SA suppressed because it was insistent on being “revolutionary” (too Red as someone earlier said!). Hitler had now had the power he wanted, there was no need for more revolution. Killing Roehm, suppressing the SA had the added benefit of removing those that knew something possibly tawdry about “Der Fuerher”, well that was icing on the cake.
In Liberal Fascism, Goldberg points out that any acolyte whose flavor of Marxism was a bit different than the Dear Leaders (either Fascist or Communist Dear Leader), or just plain pissed him off, was labeled as the other flavor of Marxist and executed.
Calling Roehm and others “revolutionary” or, more likely, “communist” was the kiss of death to this bunch.
