So let me just be clear. You are saying that Somalians are predisposed to commit fraud in ways that Americans are not such that having any Somalians immigrate to the US will increase the amount of fraud here and overall make society worse?
And you want me to believe that this isn't bigoted garbage?
So you don't believe that immigration of millions of people from let's say India (my country) which has corrupt institutions and people generally lack civic sense (littering etc.) will not cause issues to America and Americans ?
