If there was an alternative to meat that as you say is indistinguishable, I certainly would prefer that than having to needlessly slaughter an animal. Having said that, I have not eating anything that does compare (a few mushrooms can be close). I simply love meat too much, perhaps the way I was brought up.
I've tried quorn but think it tastes awful, they just don't have that umami taste I crave. Having said that, I don't eat meat everyday. Probably 4 to 5 times a weak and I never eat processed foods, so no nuggets for me lol.
Nice piece, I think my meat eating brain did try to block out some of the very good arguments there.
It can be a hard habit to break. I happily ate meat for about half my life, but over several years I reduced it and eventually just stopped. I don't really miss it now.
