Let them come... but let them do it LEGALLY, become citizens, learn the language of the country, pay taxes, and vote.
Maybe you should tell the people setting limits on how many Mexicans can enter annually at the hobknobbing and screaming of racists and putting high costs on immigration to the US that.
And who knows, they might listen to a voice of reason, instead of the racism that appears to be rampant these days against Mexicans. Really, besides what the
feds do, are people
really favoring them?
