This is what it's always been about - everything else was just an excuse, a pretense. And it will not end until either we are destroyed or this ideology is. You want to compromise? To make nice and stop making them mad at us? To give them money to build better schools and hospitals? To show them the benefits of democracy? There's only one thing that will appease them, there's only ever been one thing, and any negotiation, compromise, argument, or discussion of any kind is only for the purpose of better positioning themselves to achieve it.
These people are driven to a literally murderous rage by a cartoon. But don't think that the important point is that it is something as trivial as a cartoon. No, it's an opinion that enrages them. The expression of any idea that opposes their ideology is a threat to them.
But this is an ideology explicitly opposed to ideas, not just certain ideas, but ideas in and of themselves. Every idea is in opposition to their ideology.
Even taking our freedom would not be enough. They would know that we still have ideas, and that the very existence of those ideas and a mind capable of producing them threatens to undermine the glorious purity of their ingorance, their holy emptiness. Only death can fully eliminate the possibility of an idea. They seek death of the mind first, and when even that isn't enough, death of the body - preferably in pursuit of as many other deaths as they can create. Only through death can they assure themselves of a completely mindless, idea-less state. And only through our deaths can they assure that the world and the people they leave behind will not be contaminated by ideas.
It's hard to believe that such depravity is real. It's inconceivable that anyone human could want nothing - not to be free of wants, but to literally want nothingness, void, null. It's tempting, almost irresistable to try to find some reason, some rational, concrete position that would at least make it understandable, correctible. But there is none. Believe it. Wrap you mind around that one almost literally unbelievable fact.
There is no rational position, there is no gross error that leads them to a mistaken conclusion that freedom is flawed in some way. It's far deeper, far more evil than that. If freedom were perfect, they'd hate even more perfectly. It's because freedom is something, that they hate it. When what you want is to not exist, then every thing and every body is just an obstacle to be destoyed.
