Because when they fail to assimilate and they continue to crimes, they will be really easy to blame for the fall of Germany.
I wish the European countries could keep their unique identities without being accused of Racism, Islamophobia or bigotry.
No one fusses at all when Japan limits foreigners residency.
No white Europeans are moving to sub-Sahara Africa and when they did they were called racist colonizers. Same with Every place where Caucasians move.
It’s OK for other peoples to invade Caucasian homelands, but cultural appropriation and colonialism when whites enter their “domains” and try to assimilate?
It’s not racism or Islamophobia to want to protect your European, Christian homeland. There’s a plethora of Muslim countries other Muslims can go to.
