And I believe that even that is false.
What Mexican peasants and Indians mean by "religion" and what the Christian backbone of the Right mean are so totally different as to be a meaningless trope. The daughters of Mexican and Central American peasant immigrants (let's stop the use of "Hispanic", itself a meaningless term) get pregnant early and have lots of abortions. And our "modern" construction of "homosexuality", that stirs up so much nonsense among white Leftists, is meaningless in Mexican peasant culture.
I also get tired of hearing about how religious, conservative, and family-oriented "Hispanics" (i.e. Spanish speaking American aboriginals) are. If by "religious" they mean retaining village superstitions, going through the motion of kissing icons and using religious imagery in gang tattoos, then yes, they are religious. If by "family oriented" they mean having large numbers of offspring who they can't support financially and won't raise and discipline, yes, they're "family oriented." If by "conservative" they mean following the same dead-end behavior patterns that lead to indigence, ignorance, and poverty for generations, they are indeed "conservative."
