What could be more moral than saying no one should be forced to care for another?
I see your morality only extends to taking care of American lives only. So I guess you let the guy die if is not American? See Leviticus 19:33-34.
Who is the “we” you refer to and just how do you propose to get “we” to take care of Americans?
Illegals should not be in the country for us to “care” for. No other country in North America does this kind of abuse to their people.
And it is not abusing you to help take care of an American who is really too poor and weak (handicapped) to take care of himself. There would not be that many of them that you would even notice if it was done based on true need.
