The burden of proof is on you. Simple. And you still have provided no argument, why would you be against the entrance of Syrians, are you also against the entrance of all the other non-europeans? Because Syrians are a drop in the ocean if you compare to other migrants, why would you be opposed to their entrance and not to the entrance and permanence of dozens of other groups that are more represented than Syrians. You know , when you present an opinion it's also supposed to have some sort of argument.
"Christian love bears evil, but it does not tolerate it. It does penance for the sins of others, but it is not broadminded about sin. Real love involves real hatred: whoever has lost the power of moral indignation and the urge to drive the sellers from temples has also lost a living, fervent love of Truth."
- Archbishop Fulton J. Sheen
