People have made it very clear to me that Timothy McVeigh, who blew up the Murrah Federal building in 1995 was not a Christian, the connection between that vicious, inhuman act and the Waco, Texas incident notwithstanding. He couldn't be, you see, by virtue of the fact that he did such a thing.
It's too bad that Muslims who are horrified by terrorism aren't given the benefit of the same rationale, but I'm still waiting to hear about Anders Behring Breivik. Despite the initial prejudice that had the Oslo bombing and the murders at a Summer camp as the work of al Qaeda, it looks like Breivik, identified by a survivor as the attacker, was a Christian Conservative disturbed by the presence of other cultures, other religions, in Norway. Would he fit in with a spectrum of Americans, from the Aryan Brotherhood to the Tea Party, trying to promote our intentionally secular Republic as a "Christian nation" and perhaps an exclusively Christian nation?
How long can we go on pretending that religious tribalism of any denomination hasn't been and doesn't remain a potentially destructive, oppressive and communicable human vice?
