Why are so many of you SO against veggie-based meat substitutes?

They're getting really good at this shit now. Have you tried beyond meat burgers? Flippin beefy!
But even beyond that, i've seen people get [u]mad[/u] about the idea of a hypothetical meat substitute that tastes just as good.

Why wouldn't you want to eat something that didn't mean taking an animal's life if it was just as god or even nearly as good as the real thing?
