Ram, I wouldn't call it western, that sentiment is global.
I was at a neighbour gathering some years ago when my neighbour's brother brought some moose meat and distritbuted it. He hunts when season is on. Of those there, everyone loved meat. But when asked whether they'd participate in the dressing of the game, no hands were up ('cept mine). Back in Sg, the generation before mine (dad, uncles) all went outdoors to catch crabs, frogs, etc. during the sixties and seventies. Today, none of my younger cousins have ever killed a chicken. I was the last. My nieces and nephews know chicken as KFC, Hainan Boneless. None have ever held a chicken while it bled to death. If they did, they wouldn't eat it.
Perhaps I overstated when I said someday, we'd all be Vegans. More accurately, it should be more and more will be vegans. My daughter (Primary school) already questions me and my wife whenever there is a whole cooked animal on the dining table (turkey, duck) on occassional feasts. I reply saying the pepperoni and sausage she so likes are no different, but there is change. She prefers cheese.
