Is somebody forcing them to be here. There are plenty of muslim only countries in the world if they feel uncomfortable here. Are there any Christian only countries in the world? The Vatican doesn’t count.
In a way, yes. They are compelled by their belief system to conquer and bring non-muslims to submission. It's the long game. They are guaranteed riches and sexual pleasures over the people (women, men, and children - it's not considered homosexuality if the man you are buggering is non-muslim and you are humiliating him) they subjugate while alive and houris and riches in paradise if they die in jihad.
