One place where I work one steroid head manager tried to push around one of the older engineers who was a bit on the lean side. Former Israeli airborne as well. Steroid dude got a lesson in Krav Maga.
I know a gay guy who maintains his IDF special forces training and physique. He carries no sort of entitled gay mentality or even external clues. I saw one guy, who knew who he was gay, come close to provoking a confrontation about it until a mutual friend whispered in his ear. The guy couldnt get out of the room fast enough.
Bottom line always assume that anyone can kick your ass.
