No one is going to approach your post, probably, and it would be dumb of me to, but I will because I enjoy being dumb on occasion.

Of course they are going to open the borders. Of course they are going to let an out-group entrench itself at your doorsteps. Of course they are going to silence dissent on the matter. Of course they want to make it politically incorrect to talk about such matters. Then there will always be two opposing sides and no position of understanding both.

Don't let what happened to the US (and many other countries) happen to your countries. I was considering posting a post of my own about this topic because I had seen some... interesting posts from certain people from countries like yours but I might as well just say some of those things here.

Okay, I'm sure you've pored over a lot of the facts and data already so I think I can dispense with citing anything, everything is easily searchable.

But a TL;DR would be that in creating an image of a Muslim welfare queen as they did in the US with the image of the black welfare queen, they can dismantle safety nets used by everyone by appealing to the conservative's desire to constrain resource use to whites, they're going to try the same approach in Scandinavian countries with African/Arab immigrants, as they have in Britain with Poles and other immigrants, as they tried in Australia with Asians, etc. etc. etc.

Everyone is a little bit correct, everyone's getting a little bit pissed off, everyone needs to realize that you can't have out-groups in chicken and egg problems of "they don't get hired because they aren't integrated, but they won't integrate themselves because they won't get hired" which are statistically, scientifically true outcomes of minority groups a lot of the time and depending on which ones you're talking about in certain countries could easily be solved, but the host nation enjoys playing a game where integration is made impossible just as an excuse to mess with everyone.
