1. They already fled the war when they crossed the Syrian-Turkey border. They were safe in Turkey, Greece, Macedonia, Serbia, etc. They only stop for countries which give them free money and a privileged status.
2. They are not refugees anymore but economic migrants.
3. Most of them are not even Syrian. Most of them are young able-bodied men, not defenseless women and children.
4. Europe, it's local inhabitants and it's working class have no responsibility into all of this mess, and Europe should not be getting ruined and degrading its neighbourhoods or endangering their peoples by importing millions of undocumented foreigners.
5.Yes, it's ok to help anyone in this planet as long as we can afford it, in the case of Syrian refugees the thing to do is to create temporary refugee camps in the neighbouring countries surrounding Syria, monitored by the UN and defended by the Blue Helmets and an international peace-keeping force. They will receive international well organized aid, food, medicines, the kids will receive scholarship, etc. and when the war ends they can go back to rebuild their country.
6. In the real world, in the jungle with limited resources and extremely dangerous people and organizations that we live in. If you want to protect others start by protecting yourself and the ones closer to you instead of endangering them! Develop this mentality and you will build solid foundations, then you will know how to make a safer world for everybody instead of drifting eternally into a demagogic spiral of self-destruction.
