Social justie whack-a-do defending Islam

[Cato]

There's a perfectly cromulent word for people like that: Islamists.

Is·la·mism/isˈläˌmizəm/
noun
Islamic militancy or fundamentalism.

There's a huge practical problem with this distinction. There is no way to differentiate based on appearance meaning you will only have a fraction of a second to ponder your new discovery prior to losing your head or transforming into flying mince. Until Muslims affect the change required to rid themselves of Islamists, they will simply have to deal with the fact that unfamiliar non-Muslims will necessarily regard them with a certain level of suspicion until ensured otherwise.
