Okay DramaQueen - so what did you read & what "TV special" did you see that supported your incorrect statements that there are different kinds of "flesh"? Because frankly, popular media these days is pretty accurate re: this stuff.
There isn't anything I can supply to support your incorrect statement that some flesh is meat & some fish & some poultry, because it's way too wide a field. Again - FLESH IS FLESH. IT'S ALL THE SAME. Unless you're speaking religiously, & you have yet to state that that's what you're talking about.
It's up to the individual to decide whether they wish to not consume ANY animal flesh (mammal, poultry, seafood), or to not consume any portions thereof.
Beef is flesh.
Veal is flesh.
Pork is flesh.
Chicken is flesh.
Turkey is flesh.
Fish is flesh.
Shrimp are flesh.
Clams are flesh.
Mealworms are flesh.
Crickets are flesh.
Get the idea?
