If it tastes good, what's the difference?
Spoken like a true lizard. It can't possibly taste as good as the real thing, but we can forget what the real thing tastes like after a while, and I'm not willing to do that to my potential children and frankly, madam, I'm appalled that you're willing to do it to your actual ones.
If that were true, the KKK would be cannibals.
It's not absolutely impossible that it could taste all right, and most of what we do with meat (hamburger, whatever) only requires crap. It's not as if cows are going to be extinct.
(Admittedly, I don't plan to eat this stuff.)
I think what LB is trying to say is, "I hate America, and the red-bloody goodness that drives it."
They don't have comments over there, but there's a 50s SF story that mentions an entire urban population fed by "Chicken Little", a chicken liver tumour growing rapidly in a vat. Better than the "mechanically recovered" filth that goes into cheap hot-dogs..
"In vitro meat is people! It's pee-pul!"
