1) Most of the "refugees" are not Syrian. The host countries didn't require identification. Africans, pakis and arabs seized the chance to move to a first world country and live off welfare.
2) There are ISIS terrorists (professional rapists) among the "refugees" . Russia is bombing the shit out of them so they had no choice but to flee.
3) By promising welfare and housing, euro leaders ensured they got the most parasitic kind of people. Those who made it had to cross borders illegally, sleep on the street, stay in camps, hitchhike ..etc No decent person would agree to go through this unless he has to.
4) It's a jewish plot to destroy Europe.
