Bigotry is a state of mind where a person strongly and unfairly dislikes other people, ideas, etc. Some examples include personal beliefs, race, religion, national origin, gender, disability, sexual orientation, socioeconomic status, or other group characteristics.

complete intolerance of any creed, belief, or opinion that differs from one's own.

So by this definition continuously depicting the prophet especially in a negative and unsavoury way shows intolerance and a lack of respect for that religion and belief.

But you rather protect your freedom of speech to no ends, even if it means insulting and shitting on other people along the way. because fuck it its your right to be an asshole.
