Actually the left seems to enforce the nomenclature changes calling them "migrants" rather than illegal or economical immigrants.
Doesn't mater how you paint the picture the moment these guys ended up in Turkey and kept going west they became economical immigrants, and they don't even stop at the first European country they get into they strive to go deeper and deeper to countries that (they think) will give them more benefits.
Heck as we speak you have anywhere between 75,000 and 300,000 "migrants" holding their fort in France (Mainly in places like Clais, Dippe, Rouen etc.) waiting to get into the UK and constantly avoiding registration in France in order not to get "stuck" there.
And the fact that you can hardly have an open discussion about this without being labeled as a racist is just mind boggling and the worst part is that it will make things 100 worse down the line because the pressure that the left imposes on everyone will just means that the whole situation will literally explode when it will reach the boiling point and were not that far off.
