You’re wrong about the current religious situation in Argentina. Since the Ks took power, they’ve been methodically attacking the catholic Church, like good socialists. The methods used are similar to the ones applied in USA: Media campaigns, the spreading of every single bad thing they can dig out about it, never mention any of the good things they do, mocking their traditions or down right banning them so as not to “offend” others.

Soon enough you receive “happy holyday” letters or even more repugnant “Happy Xmas!” ones, lets be careful not to offend anyone with the word “Christ”, God forbid. (the irony)
And then people wonder why you have kids that consider Marilyn Manson a god (or even more evil, Miley Cyrus :-) ) Why a normal looking guy from UK becomes an Islamic fanatic and tries to bomb his own home town, why a kid goes to school with a gun to shoot people. In the good old days when those evil Christian families and their values where the norm, kids practiced target shooting in their schools and you didn’t have a massacre every week. In my school, they shot with 22LR and 7,65 Mauser, no one ever got shot.
You think America is at “risk” of becoming extreme Christian? 1) Why would that be a bad thing? 2) Its becoming more atheist, socialist big brother new world order, not conservative Christian.
