There is simply no way to tell if you’re importing a lazy muslim who will be a perfectly good neighbor or a devout but dishonest one who will kill thousands given the opportunity.
No. Way. To. Tell.
And similarly no way to tell when the good ‘lazy’ muslim neighbor will suddenly return to the religion of his forbears and kill thousands at the first opportunity.
Let me ask what your spiritual background is.
A gates-of-hell problem has a church solution. Jesus said so. Jesus will actually DO things if you love Him rather than loving the stained glass windows that you have put pictures of Him on.
