I won't get into the whole debate, but I think it's a bit misleading to say that meat took the place of the food God intended for us to eat. No point in discussing it since there are scriptures for both sides (I've had this discussion a thousand times over, so I know all the SDA scriptures and I know all the opposing ones).
But yeah, I had that morningstar stuff before. I will never, EVER forget that day. I had Sabbath dinner with a guy I was dating at the time. It was my first time meeting his parents and his mother made a huge Thanksgiving-like spread. I'm a finicky eater, but I had never had a meal where there was absolutely NOTHING that I eat being served. It was almost as though she intentionally cooked all the foods I DON'T eat. I was so embarrassed and uncomfortable. I tried to eat some of it just to be mannerable, but I started gagging with the meat pattie thingy. I probably would've been okay if I hadn't asked what it was.
