@maxdancona,
It's not a religious question for me.
I don't follow Islam or Christianity, but recognize that both can be forces of good and both can be misused by the less than honorable.
Barbarous acts in the name of Christianity are no better or worse than barbarous acts in the name of Islam.
I'm not sure why but you seem to want to equate the current excesses of Islam in the Middle East, with the current excesses of Christianity in the US.
There is no comparison.
This isn't because Christianity is better than Islam, it is because American culture is more advanced than Middle Eastern culture.
American Christian zealots may want to deprive gays of certain rights, but Muslim zealots want to deprive them of their lives. Neither is a good thing, but they are not equivalent.
I'm not defending Christianity. I've no doubt that its practice in backward societies is every bit as nasty as the practice of Islam in the same societies.
There is simply no Christian equivalent of Sharia in modern nations where Christianity is practiced. This doesn't mean Christianity is a superior religion, it just means that modern cultures are more liberal than those stuck in past centuries.
BTW - Sharia is not a fundamental element of Islam, just as The Inquisition was not a fundamental practice of Christianity.
