What an incredible waste of time. I am not vegan, but people's cultish worship of meat has got to be one of the most annoying and petty ways that food is politicized. No one is going to be fooled or confused because you call something a "vegetarian steak", this is purely conservative reactionism.
Seriously, what is the real-world impact here? Imagine for a second that some miracle vegetarian steak could be confused for a beef one. Why does it matter? Someone might accidentally eat a vegetable?
