If their home countries aren't shitholes then why are they here? why do they not want to go back?
Why are you calling their countries shitholes? Have you been there in the past?
Yes and I would never set my foot over there. You can't compare to the US, other countries are inferior in every way.
The situation in different countries are not the same and I do not think it is a productive thing to say that their countries are shitholes specially if they do not have any control of what is happening in their countries. I suggest that you rethink what you are saying and see if you can help immigrants with sheltering a family in your home, just if you can or try to donate food or money in your local asylum shelters.
Everyone in their country hates each other. I came here because the US is heaven on earth.
I'm glad you like the US, but your experience if your own and it's not fair to speak on the behalf of others from your country. Every country has things to be proud of, and things to be ashamed of. How about highlighting what your country does right, in order to give off better impressions of it to others?
