It's amazing how people have to look on social media to be told that they are seeing foreigners everywhere, rather than - you know - actually looking outside where they'll see it's all bullshit. But they prefer to believe what they've been told rather than what they see.
You see what you want to see. If this guy says that all he sees is foreigners, it’s because he has a predisposition to look for foreigners. If foreigners living in your area doesn’t bother you, than you probably don’t notice them as much, because they are just part of normal everyday life.
How does one see a foreigner? Are people wearing their birth certificates on their shoulder? Is there a practice of tattooing coordinates on foreheads?
They mean 'brown people'.
And people who “dress funny or “talk weird or otherwise haven't been going to the same church or local events for eight generations with wildly detailed family history known to everyone. Or at least that's what the bigots around my way mean.
