But I still think the down-voters are taking it personally. I don't believe anyone is actually being chastised for their position by this commenter. I took it as offering another option - instead of telling someone who likes meat that you have a great substitute that tastes just like meat and they'll never know the difference, try saying "there are many ways to prepare any of a large variety of vegetables - maybe you can enjoy vegetables as much as you enjoy meat if you find some recipes you like". Maybe those dishes will taste "meat-like" or whatever, but there is value in saying "Stop trying to fake it. Embrace the choice to do it differently."
For the record, I personally believe that this is a more honest tack for someone who is pursuing the option for ethical/environmental reasons.
