Islam is pretty much incompatible with every other faith out there, which makes sense considering it's essentially some desert warlord's Abrahamic-flavoured cult of personality that managed to somehow live on after his death. I view it in the same vein as how the religion of the Huns was based on the idea that Attila was given a sword that represented his right to rule the entire world, only if this cult carried on after Attila kicked the bucket and somehow grew to consist of 2 billion followers. Every case where Islam has come into contact with other religions, it's always ended in violence, and usually mutual violence. They forcefully converted most of the Jews and Christians of Arabia (killing those that refused to convert) and absolutely annihilated the local polytheists, turned Zoroastrianism from a major religion into a tiny minority faith, and subjugated the Hindus and Buddhists of India on-and-off for decades at a time, just to name a few examples. Granted, the same applies to Christianity, but the Christianity of old that converted people by the sword has been a dead and buried concept for centuries, only remembered fondly by fat NEETS with £50 wish.com crusader larp costumes.
Some people seem to hope Islam will reform and become as accepting as most other major religions, but that is so optimistic it borders on complete delusion - the Quran is the unalterable word of Allah, passed onto the Prophet Muhammad. Anything that is written in the Quran cannot be removed, only interpreted in different ways, and there's only so many ways you can interpret those texts. Any attempt at reforming Islam will always hit this brick wall where there are calls for violence and submission against the infidel in the Quran that can't be removed without making the reformer in question a heretic. And being a heretic is even worse than being an infidel in the eyes of Islam. Any Muslim that tries to reform Islam will inevitably end up in the boot of some jihadi's Toyota pick-up without his head.
We could've gotten close to a potential reformation of Islam in the 70's, but then Persia had an Islamist revolution, and the Saudis had some jihadis seize the Great Mosque of Mecca and cause them to go balls-deep into fundamentalism, and begin spreading said fundamentalism to Western mosques through copious amounts of oil money.
Unfortunately, as it stands, there's no real solution outside deportations of Muslims in non-Muslim countries and non-Muslims in Muslim countries, and that would have it's own myriad of issues regarding cultural clashses and human rights.
