A lot of food handling instructions in religion are rudimentary sanitation practices. For example, food must be consumed same day, not left out. Don't eat raw shellfish. Don't drink blood. Wash your hands.

The reason these practices are in place are historical

Think about a time before modern sanitation. You eat THIS meat, you fucking die. So obviously God doesn't want us to eat it because otherwise he wouldn't have made it a dirty, deadly meat. Even today, these meats kill people occasionally.

I'm an atheist, but I think it's still worthwhile to understand the perspectives.

Cares about the meat you eat and the meat you beat

And isn't it funny how the gods are always concerned with the same things their worshippers are? It would be odd to care deeply about regulating the sexual and dietary habits of the ants in our backyards. If god(s) were real I'd expect their interests to be wild and beyond our understanding, and not about what hats humans can wear and what meat is acceptable.

If you read through the stories that define them, it makes a lot more sense. Blood and sacrifice are intertwined with life and righteousness. God is holy and set apart, and can't be in the presence of less -- so their lives and habits are built around remaining in relationship to their God.

So the careful handling of death, food, and blood makes perfect sense from that worldview, whether you personally agree with it or not.

organized religion is and always has been about using laws to control people and take their money through brainwashing backed with death threats where and whenever they can get away with it

Just wait till you find their opinions on the oppsite hole.

Arguably. I think a lot of lab meat currently uses massive amounts of FBS instead of alternatives. Though I guess many vegetarians don't have a problem with renet.

There isn't really a central authority for deciding if it's vegetarian or not though.

Technically is not an animal product so I guess it is vegetarian but also at the same time it's still meat so it isn't.

I guess it depends on what your objection to meat is. If your objection is based on animal cruelty then I guess it's probably vegetarian but if your objection is based on dietary restrictions (religious or otherwise) then obviously it's not.

They already did a big wooly mammoth meatball, so you're not alone there.

Yeah I wanna try some Dodo bird, must have been good if it was hunted to extinction.

There are a handful of organizations that will certify your product as kosher. Some people trust one organization or another, some trust any of em, some use their best judgement in general. A large organization of Rabbim agreeing on its kashrut status could hold a lot of sway, though, and be a catalyst to start a conversation over many tables of "Should we eat this?"

Now, what I'm curious of is what the meat qualifies as.

Is it milchig, fleichig or pareve?
