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.
