How? And i'm not putting you down in any way.
Well let's take a look at the facts.
Meat: Grown for consumption, Packed as tight as possible in corrals to increase yield, killed and processed for consumption, When eaten, animal is long dead and cannot scream in mortal pain from being eaten.
Veggies: Grown for consumption, Packed as tight as possible in farm beds to increase yield, Harvested alive to preserve freshness, When eaten, is alive and doesn't have said mouth to scream in mortal pain from having chunks of it's flesh rendered from it's body.
I dunno if not having a face or mouth seems to not be a good enough excuse, otherwise vegans would love shellfish, muscles, ect. Yet still don't because it's "alive" and still considered an animal.
