Because it's little more than xenophobia, which has always been extremist.
You don't want people with radically different value systems being allowed to migrate without making efforts to integrate themselves? Sure, say so. That's a reasonable position that can be debated. Maybe you'd be OK with asylum seekers fleeing for their lives, maybe not, to be discussed.
You don't want anyone different to come to the country? That's xenophobia, and considering the demographic challenges facing the EU, stupid. And of course the funny thing is that most of the people espousing those extremist views and voting for the "migrants bad" parties are living in the countryside where there are practically no migratns and everyone knows everyone else. Cities, where those migrants (be they Afghanis or Ukrainians who ran for their lives, Sudanese looking for a better life) are actually concentrated, are markedly pro-much more open to migrants parties.
Welcoming all migrants can work in countries with no social net like US in their biggest boom. Come and work. EU countries are stretched and more and more people with low to no skills are gonna be really hard on the budgets. They cant even guarantee to pay people born there nice retirement in 30 years.
Are you under the impression that anyone can just come into an EU country and start receiving aid?
There are programs to help asylum seekers (people literally running for their lives) settle in, but there are lots of criteria to fill to be able to claim that, and it takes weeks to years of processing to validate your claims you're indeed running for your life and there's an actual risk for your life.
I understand that. But the migrants also need housing and food while they wait. I am absolutely for some kind of immigration. But not for "everybody that comes here will stay". And absolutely for trying to engage people into european society. Fundamental islam is a real thing. Second generation of immigrants is getting radicalizes and european union needs to do something with it. And if somebody accuses me on hating islam, i dont like all religions the same.
