Freedom of religion is also freedom from religion and a right to be disgusted by particular religious figures. No one owes even an ounce of respect to any bearded prophet out there, this is literally the essence of a liberal society: the very absence of blasphemy (that you recast as "Islamophobia", same thing under a different name, only sounds more modern) as a concept.

Muhammad had between 400 and 900 POWs of the Banu Quraish tribe beheaded. Not calling this terrorism means twisting the very meaning of terrorism into pretzels.
