Well, I'd definitely say that immigrants can cause various problems especially when it comes to monocultural nations.
Then again, pig americans your whole trashy country is made of immigrants and yet you have these ridiculous immigration policies. How hypocritical can you be? You're the street trash that got evicted from europe and now you act like you're actually something special and original. Tell you what, you're nothing but a bunch mixbred immigrant and that's there is to it.
