The refugee thing is fine, it's happened over the centuries.
The "orange man bad" reference we could have done without. That's a little distasteful. And imo, an unnecessary addition.
That said, yes, being worried about who's sneaking in disguised as a refugee is also valid. I could give some real world context but I don't need to. Look at my location, that says it all.
But yeah, should need to chill out. Getting super angry about stuff is pointless.
