I know a number of Hispanic Catholics, and none of them have the attitude you describe. While I know that that attitude exists, I believe it is not common with Hispanics who take their Faith seriously.
"We are here to show White Anglo-Saxon Protestant America that we are not going to be the ones deported! They are!"
"Kill the gringos!"
"We are a proud bronze nation and a proud bronze race!"
Not to mention these immigrants suck up the welfare programs and hospitals having to take care for them, with those "evil gringos" paying for their welfare with our taxpayer dollars of course.
As for "gringo exploiters", well, America did exploit Mexico and other Hispanic countries a great deal. Cuba and Panama as well.
We were good enough to bail out Mexico and Brazil constantly with the IMF, a gratitude they used to get more money. Despite FDR's Good Neighbor Policy Cardenas nationalized the oil companies. We paid Mexico back for the territory we took during the Mexican-American War (territory which they used to ambush and kill American soldiers by the way), Mexico has refused to deal with the immigrant problem and even encourages immigrants to come North to this country, we tried to save Cuba from Castro but failed because JFK refused to use air and naval support, we intervened in the Dominicna Republic in 1965 and Grenada in 1983 to stop a Communist takeover, etc.
Minorities can all agree on one thing, and that is getting more money out of "whitey."
