You are welcome to ignore my warnings, but why would you ignore the explicit warnings of Muslims? Most people could consider that to be a fairly obvious and wise move, but not the useful idiot Leftists taken in by the “refugee” crisis, that, oddly enough, super-rich Arab countries like Saudi Arabia could solve immediately.
Islam is executing (no pun intended) a successful strategy via violence and by simply reproducing in vastly higher numbers. They wisely exploit the West’s — and especially the Left’s — general short-sighted nature, cowardice, selfishness and hatred of children.
Also see German hamlet (pop: 100) to welcome 750 new immigrant residents. Gee, what could go wrong with that?
