In my view Photoshopping her head on a hulk body is not fair game.
Is creating a caricature of the Prophet Muhammad fair game? In my view it is. That’s the way free speech works, and that right should be defended in my view, even if you disagree with what is depicted. If creating a caricature of a Prophet is fair game, then so is creating a caricature of the Star Wars character Rey. If it was a caricature of Daisy Ridley, that attempts to ridicule her personally, then I would agree with you.
That’s free speech - not toxicity. For many people they would consider a caricature of the Prophet Muhammad to be toxic, and in my view rightly so.
