Once you’ve put the food in front of them, you’re done. They’ll either eat or they won’t. Not your problem, not even your business really. If they want to go collect their 72 virgins for killing Christians and Jews, let them!!!!
It is only a problem for you if you wish it to be. Don’t Jews have enough problems just surviving without getting all worried, perplexed, upset, tied-into-knots over silly crap like this?
Stop fretting so much, go out and build some more houses, schools, industries, universities, and pizza parlors.
Actually, one of my wife’s aunts starved to death in a nursing home that took that attitude. If it’s good enough for Aunt Bertha at Shady Rests, it’s good enough for a freakin’ terrorist whom international law says ought to be dragged out and shot like a dog anyway.
