Well if they are you're probably getting a greater amount of other selfish, unpatriotic people to replace them so idk if it's a net gain from your pov.
Depends on why they are there. Refugees tend to care about the country they came from more and the one they landed in they view as a temporary shelter.
This is totally untrue. As long as it's selfish, unpatriotic people leaving, I couldn't care less what their skin color or sexual orientation is.
