> Edit: more to the point, until Victorian times, Muslims were most commonly referred to as Mohammedans because the English-speaking world just assumed Islam is to Muhammad as Christianity is to Jesus Christ. People might have thought that way about Muslims (I'm actually quite sure that they did), but the term alone doesn't support that at all: Christian reformation movements that wouldn't dare to consider their namesake a prophet, much less something more deic (is that even a word?) are routinely referred to by the name of some person who is connected with the theological delta from where they split off. Lutherans surely didn't extend the trinity into a quad for example.
