I say we stop here. You have no desire to have an "adult" conversation and I have no desire to keep going back and forth with you in this fruitless exercise. There are others willing to have an actual discussion that doesn't consist of "You're wrong, now go use Google to prove me right".
...and with that.
I'd urge you to continue. You're making your points quite well, and while you'll never change his mind, there are others reading who haven't yet made up their minds. Most users are lurkers, they just read and don't post much. Keep presenting for them.
I fight some battles, others I leave. You're doing well with this one.
