Every time someone brings up the "yeah, let's see what happens if you try to build a church in Saudi Arabia" idiocy, I want to ask "Um, aren't we supposed to be better than them?"
Saudi Arabia is one of the most repressive regimes in the world. The House of Saud are scumbags, and I wish they would all drop dead, along with every single member of the religious police.
I feel the same way about the Christians in Uganda who are trying to pass laws making homosexuality punishable by death. They should all die.
But this is America. We're better than Saudi Arabia (who isn't?) and Uganda (ditto). We should be trying our best to live up to our ideals, the ones our young people are dying for in Afghanistan and Iraq. Religious freedom is one of those ideals.
Just because they CAN build it there, doesn't mean they should.
No, it doesn't necessarily follow. But there are good reasons to build it, and to build it there. There are lots of Muslims in that area, and lots of non-Muslims, and while New Yorkers got over most of the anti-Muslim fervor pretty quickly, there are still some tensions. This is far enough from the WTC site not to be in anyone's face (only New Yorkers really understand that, apparently: two blocks in Manhattan is a whole different neighborhood) but close enough that people might go there to learn about Muslim culture and history, and perhaps learn what those of us who knew Muslims even before 9/11 have always known: Al Qaeda and their ilk are considered outcast heretics in Islam.
You might find plenty about Islam that's objectionable, and so do I. But killing innocent people--even enemy noncombatants--is expressly forbidden in the Qur'an. Muslims are extremely reluctant to say "he's not a Muslim" about anyone, but all the Muslims I know are quite willing to say it about Osama bin Laden.
One of my father's graduate students told me that his reaction on 9/11 was "Oh, no, what are you doing to my country? What are you doing to my religion?" I think that says it right there.
