Roehm is still a threat to Hitler, period. When he said that the SA was going forward, with or without Hitler, that was viewed as High Treason by the SS. Even if Roehm kept his...preferences to himself, when Hitler kicked down the door at that inn and found Roehm's driver in bed with another SA man, that was enough, and Goebbels has another reason to justify the purge. Both the driver and his partner were taken outside, stood up against a wall, and shot by the SS, then and there. Roehm would've been tarred with the same brush, and nothing really changes. Btw, the whole Night of the Long Knives was called Operation Hummingbird by Hitler, Himmler, Heydrich, and Goering. (he was in charge still of the Prussian Police and the Gestapo)
