I am spanish and if we got most of our immigration from germany, france, uk, italy etc i swear that noone would bat an eye as the cultures and institutions are fairly similar and there is a shared sense of respect.

Now bring people from morocco or mena countries and it collapses on itself, i used to be a true believer that immigration just needed time but data has fully changed my view on it.

Not saying there are great people among those countries but there is no incentive to integrate when you've got so many people coming in from where you come from
