Sorry that you met condescending assholes. Some people just have the urge to feel superior over others for absolutely silly reasons. The rise of meat alternatives is one of the few things that make me optimistic for the future, along with renewable energy, electric cars and heat pumps. Factory farms are so much worse for the environment and animals, of course we should embrace alternatives to the worst option.

Prices also go down with more competition. There basically wasn't any market for meat alternatives 10 years ago, now it's growing quite fast. In 5 years, many of them will likely be cheaper than meat.
