Which do you prefer? The values of America or Mexico?
There are 250 million americans, and around 9 million mexican immigrants (including around 5 million undocumented). I fail to see the problem.
Mexico is a strongly religious (catholic) nation. Abortion is a no-no, they work hard for their money taking jobs most Americans won't, and believe strongly family (and they send back a PAINFUL percentage of their income to support those families this I know first hand), are there any particular problem with these values?
