Not a defense, but rather support for your opinion, just take one look at Europe. Previously, they welcomed Syrians and middle Easterners escaping conflict. But in the last years, right wing majorities have emerged and grown based on increased crime and general nuisance, many are now against immigrants. Just yesterday the Danes are insisting on eliminating these nuisance loud "calls to worship" from Mosques. Immigrants that are not really being hired by locals, or not successful starting their own legitimate businesses, too often turn to organized crime - - they have to make a living somehow. Witness the violent protests recently in Ireland against immigrants. Witness all the bombings in Sweden, and of course the rapes of local women. Many of these immigrants come from less lawful countries, where it's often "dog eat dog" for survival.

I can't speak for Europe but in the US crime has been on a downward slope since the 90s, all while the percentage of immigrants in the US has gone up.

A few studies have shown that immigrants have a lower incidence of crime, especially undocumented ones. I don't know of any reputable studies (in the US) that show otherwise.

The violent protests in Ireland were explicitly enflamed and coordinated by Musk and other right-wingers over social media: https://newrepublic.com/article/211936/elon-musk-race-war-be...
