Lets be honest the majority of atrocities committed around the world involve the followers of Islam. They are intransigent and unable to accommodate and integrate with any other religion. They do have form and they have had it for 1500 years.
Without wanting to get this site cancelled, I can't help but agree. Every letter in your post is the uncomfortable, but unavoidable, truth. Well I say unavoidable, but the world does its absolute best to avoid it by forgetting/ignoring history, sticking its head 6 feet into the sand, and creating a fictional version of Islam as the religion of peace, or at the very least as something that doesn't go mental as long as you don't upset it.
Humanity is facing a coming, colossal battle. If it wins, the galaxy is our oyster, with things like nuclear fusion, AI, the space elevator, and who knows what else, within reach in the next few thousand years. If it loses, humanity will be dragged back to, and then stuck in, the 7th century for god knows how long. A very, very long time I expect given the iron grip Islam has over its followers, and the vicious treatment it meats out to apostates.
And the starting conditions for this battle, when it comes, are continuously being shifted in favour of Islam by the western world's suicidal open borders attitude to immigration.
