Because they are a-holes.
Yep.
That pretty much sums it all up.
Ignorant 3rd worlders. A perfect match for a 1st world society and liberals with guilt complexes.
It’s what immigrants do. You flee the old country because its a dangerous cesspool. Finally, you arrive somewhere safe. But, after a few years, you get nostalgic and start trying to recreate the hell-hole you left.
Of course, previous waves of European immigrants did this much more benignly.
