Immoral sex has been in Islamic society for longer than the United States has existed. From selling young girls into temporary arranged marriages or forced prostitution, to wealthy Muslims keeping sex slaves locked in their palaces, to gangs of thugs assaulting not only young female but also young male tourists, they have had plenty of decadence of their own.
D'Souza gives the Islamic nihilists way too much credit. Conservatives should not fall into the Jerry Falwell/D'Souza trap.
Believe anything that you want to. I discussed an experience I had with a large group of Iranian Muslims, most of whom enthusiastically helped create the Islamic state there. It was clear to me that they hated the same things about America that many social conservatives do--especially porn and promiscuity. I suppose they especially hated them because they found them tempting. Similar opportunities for recreational sex may have been available in their homeland, but these young men were astonished (and appalled) at how easily and widely available they are here in the USA. I think D'Souza is right on target here. When the facts about the 9/11 killers came out, my first thought was "I know these guys - I know them very well."
D'Souza is just throwing the librals' "why do they hate us" garbage back in their faces. They hate us because of you, librals. No it's not because of Ronald Reagan and global apartheid and the growing gap between the rich and the poor. It's because of you, "the pagans, the abortionists, and the feminists, and the gays and the lesbians, the ACLU, People For the American Way, all of them who have tried to secularize America." Falwell was right.
