I struggle to picture this group of drinking feminists sitting "spellbound" at your lecture.
Having a german exchange student at hand was a cool coincidence.
But for future reference, not "all" of the brown shirts were executed, they had perhaps 2 million members and maybe 200 or so were executed.
Rohm did not found the SA, Hitler did, as a personal body guard for beer hall politics. The SA was founded in 1921, and Rohm did not become leader until a decade later. Rohm was around in the early days and involved in the beer hall Putsch, but by no means was he its founder or leader at that point. By the time of the failed Putsch I am sure you will recall that a fellow named Goering commanded the SA. In fact you will recall Rohm pissed off to Boliva to work as a mercenary for a number of years in there. In the early days of the SA Rohm was more of a Freikorps guy, and they eventually got folded into the SA.
I could go on, but why bother.
Oh...and Hitler never promised a free beetle to every German. I think "Josh" needs some remedial history about his homeland.
