I find it hypocritical that you find my comments to be an insult when nothing explicit was said

but when an individual is called

    * "the madman" or "possessed"
    * "a devil and first-born child of Satan"
    * a "wicked impostor", a "dastardly liar" and a "willful deceiver"
    * "a terrorist,"
    * "tyrant" a "pervert"
    * a "mass murderer and a pedophile"
    * a misogynist, a rapist, a pedophile, a narcissist, a lecher, a torturer, a mass murderer, a cult leader, an assassin, a terrorist, a madman and a looter

You say

 The parts you quoted above are not "insults" if they are directed at a sympathetic audience"
 A criticism, by definition, is "the act of passing judgment as to the merits of anything."[2] All those statements quoted above are simply that, passing judgment on the merits of Muhammad.
That's a statement by Martin Luther, one of the most notable figures of Christian history therefore worthy of noting his views of Muhammad in an encyclopedia. He was not addressing Muslims. He is passing judgment on Muhammad. ["a devil and first-born child of Satan"] By definition, that is criticism....wow.

An insult (also called a putdown) is an expression, statement (or sometimes behavior) which is considered degrading and offensive. 

A criticism is an argument against something not a profane single worded statement or label against it.  06:01, 6
