Quite an appeal but it has a flaw. The people who make that argument don't want to help the US elderly and disabled either.
That doesn't make squandering our national resources on Third World beggars right. If there is one homeless American or one dollar of national debt, we have no business slopping illegal aliens with welfare, healthcare, housing and education. If you hate America and Americans and you aren't a citizen, the best course of action is to mind your manners. WE ARE UNDER NO OBLIGATION TO SUPPORT PEOPLE THAT HATE US AND OUR NATION.
