Since that would be very out of character for an American Christian, I would certainly be surprised.
Indeed, American Christians would much prefer to shoot up a Planned Parenthood than a gay nightclub.
The numbers of Americans killed by Christian terrorism vs Islamic terrorism is a bunny hill vs Mt Everest. What a strawman.
Actually, the numbers of Americans killed by domestic terrorism is greater than any foreign terrorism. But, of course, everybody fixates about those bad Muslims.
Of course, this attack in Orlando wasn't foreign terrorism. Nor was the Boston bombers, etc, etc. In fact, with the exception of the Charleston massacre, the Sikh Temple shooting and the Oklahoma City Bombing, most of the major mass casualty incidents (Fort Hood, Boston, Orlando, San Bernadino, etc) were committed by Muslims.
Whether you agree with Trump or are like me and find his proposed Muslim ban retarded, it's intellectually dishonest to perpetrate the myth that it's still 1994 and that militia groups are still a threat. Even if they did exist outside of a handful of Bubbas drinking beer and shooting off their guns in an Idaho trailer park, how many Federal Buildings have they blown up since McVeigh?
