Forgive me, honored Rabbi.

I really am not trying to troll…
My question is serious.
Is it permitted?
Is it forbidden?

The practical implication is that if it’s forbidden, maybe I could go over and tell the arsonists that it’s a prohibition of meat and milk, and maybe that would stop them…
(Other prohibitions don’t mean anything to them.)

I’m completely serious. End of Shevat.

What’s the question? The prohibition of lying? Or are you asking whether there is actually a prohibition here of cooking meat and milk? (Of course there isn’t.)
You’re trying to prevent destruction of public property, so the question is whether it’s permitted to lie? Are you for real?
I think I’ll delete this thread too.

My question is serious and genuine.
Why isn’t there a real prohibition here of cooking meat and milk?
(I wasn’t thinking of bluffing the zealots. If there really is no prohibition, then I’ll keep quiet and suffer along with the rest of the sick among the Jewish people.)

Because this isn’t cooking but burning. It isn’t done in a pot and not for the sake of preparing food, but for destruction and elimination. Even food absorbed in a pot is considered cooked because it comes back out as food. Of course the prohibition of cooking does not depend on eating, but the act of cooking is the preparation of food.
I just now saw here a foolish halakhic opinion that you can rely on: https://www.bhol.co.il/news/106451
Of course that’s utter nonsense. My guess is that the rabbi there knows that too, and perhaps said it in order to calm the foolish zealots. But who knows…
By the way, with poultry and milk there is of course no prohibition of cooking, only of eating. This applies only to meat and milk.

Before getting all hair-splitting about garbage dumpsters, think about the household trash can, where meat and milk are thrown out together (even when wet and runny) and sometimes sit there for more than a full day — pickling/soaking. And that would bring us to the prohibition of cooking meat and milk.
