> Turn on the TV or read a newspaper to see how much crime ...

Amazingly on TV in Europe (watching 3 countries) I see how many women are killed by their partners (nicely born here), how politicians are (occasionally, mostly rarely) arrested for building mobster like organizations, how large enterprises (own by locals) avoid paying taxes.

The poor don't resort to violence? I wonder what blessed country are you in for the poor to afford to be nice. 30 years ago in the quite poor Eastern Europe (now part of EU, not that poor anymore) there was direct violence (sure, not concentrated like a terrorist attack) like mugging or rapes or just people beating others on the street because they "did not like how you look". All that without immigrants. So yeah, kind of hard for me to blame so much immigrants for all the violence.

And on that, 70s and 80s the was perfectly calm no? No terrorist attack IRA, ETA (found easy a reference https://en.wikipedia.org/wiki/List_of_ETA_attacks - 829 deaths), Italian mob and the like were "freedom fighters" probably...

I am definitely not for completely open borders. And immigration should be controlled. And some people should be deported. I just do not think it is the "largest" problem that it is presented, and I find discussing it avoiding other thorny, complex issues (energy, climate, education, etc.).
