It's interesting the different experiences people have.
I've found LLBG to be downright pleasant. I get there at most 90 minutes prior to an international flight, breeze through security in about 15-30 minutes depending on queues and often have time to spare to get a coffee and browse through the duty free shops at my leisure.
Full disclosure: I am an Israeli citizen, but I've had this experience even prior to becoming a citizen, when I was only a US citizen.
Regarding your last sentence: May I ask whether you
a) speak Hebrew
b) are jewish?
Both seems to help a lot (got some friends from DE and the US that had less trouble than I did and .. well, that might make a difference).
I'd certainly even agree that I'd prefer the treatment in IL to any body scanner/groping experience "elsewhere", but I don't like the experience one bit and get singled out more or less every time.
I've lived there for a year and travelled to Ben Gurion before and after that time. It's never pleasant and often downright insane.
