Because meat tastes better, and I want it. If I can have that taste without an animal involved then it’s all the better. If not then I’ll continue eating meat.
Vegetarians and vegans just don’t seem to understand this. Food is all about personal preference but the extreme majority of people eat and enjoy meat. They enjoy it because they find it delicious. If people felt vegetarian options were as delicious as meat we wouldn’t be having these discussions.
People who don’t have a taste preference for meat are obviously not the target for plant based meat.
