Jesus carries an AR-15? Constitution came from Jesus?

Not all Christians are stupid but some people make it difficult to defend them (and I do defend them when necessary), but this dude..... :(

William “Jerry” Boykin, the deputy undersecretary of Defense for intelligence for much of the Bush/Cheney era, and who was  in charge of the hunt for Osama bin Laden in 2003, said THIS week:

“The Lord is a warrior and in Revelation 19 is says when he comes back, he’s coming back as what? A warrior. A mighty warrior leading a mighty army, riding a white horse with a blood-stained white robe…. I believe that blood on that robe is the blood of his enemies ‘cause he’s coming back as a warrior carrying a sword. And I believe now – I’ve checked this out – I believe that sword he’ll be carrying when he comes back is an AR-15…. The sword today is an AR-15, so if you don’t have one, go get one. You’re supposed to have one. It’s biblical.”

Boykin added that “the whole concept” of the U.S. Constitution’s Second Amendment “came from Jesus.”

He CHECKED IT OUT???? With who?? JESUS carries a friggin GUN? (NOT just any gun either, no, an AR-15 - awfully specific. Does this guy work for a gun manufacturer or something??)

There's a lot of violence in Heaven, you say, where Jesus needs to carry an assault rifle? Does Moses have one too? :( How do they get guns in the after life anyway? I thought worldly possessions were left behind?

(Aside: Perfect marketing strategy for a manufacturer -- 'We make the gun Jesus carries!')

And the writers of the Constitution, who were not even Christian, wrote the 2nd Amendment because it came from Jesus? They weren't even Christians!! Yo, they weren't even Christian - and they argued Separation of church and state so why would they put Jesus..... yeah, NO. It didn't come from Jesus.

Things like this are absolutely ridiculous.
