Since he died in the service of his nation, do you have any evidence to back up your claims? Stevens, after all, was homosexual and would know Islam does not looks kindly upon his people.
He had a long track record of positive writings about Islam ever since college, supported Islamic causes and organizations such as the PLO, and was in fact a Muslim convert (to Sufism). While Sufism is considered a mystical/syncretist form of Islam and is frowned upon by mainstream Muslims and probably wouldn’t have earned him many friends, it is very strict about homosexuality (this was even affirmed to me by a gay friend who had been a Sufi but left because of that). So if he had been a practicing homosexual before that, he certainly wasn’t one after he became a Sufi.
This wasn’t a personal attack on him, or at any rate not for anything about him personally. It was an attack against the United States, and probably was also focused on some activity he was involved in.
I think the latter, in fact, is quite likely; the question is simply which one of the players needed to take him out.
His people? I would say homosexual sex defines a disorder -not a people. Anyway, I think with this observation you have pointed out the obvious delusion inherent in all leftists -they are utopians who think order is about controlling others rather than simply being responsible for themselves -they are delusional.
