ok ok, even muslism is then.

Eh? My point was that you wouldn't necessarily expect them to have thought of it. They certainly won't have thought of this bizarre misspelling.

Fair enough, I am unfamiliar with the misspellings. Musli(s)m sounds perfectly normal to me as a non-native speaker of the English language, and for a bunch of other people on the internet for that matter hence the suggestions of google.

I just tried to say that out loud and find it quite a tongue twister.
