Well, a pretty obvious objection to your reductio is that cabbage doesn't do any of that.
You are hurting the feelings of all the cabbages and cabbage patch kids in the planet now.
And lobsters are not killed clinging from dishes like that fake relate claims, (but don't allow the truth to stand in the way of a good crowfunding).
Plants are much more sophisticated organisms that most people think. What if we just don't understand their suffering when we put a photosynthetic organism in the dark for months? Plant lives matter! please send me money (or seeds).
I assume that by law octopus in UK must be killed in a fair duel now, because we didn't had enough problems with wet markets yet.
How does it feel if we take the previous attempt of emotional manipulation and substitute that for this?
"If you’re tilting it from a container into the steaming kettle, the cabbage will sometimes jump trying to escape its destine or even to hook its leaves over the kettle’s rim like a children trying to keep from going over the edge of a roof with a fluffy kitten in their broken right arm. And worse is when the cabbage is fully immersed. As a Guantanamo prisoner cabbages aren't aquatic plants and can't breath under the water!. Even if you cover the kettle and turn away to not smell its fear, you can usually hear the cover rattling and clanking as the dismembered cabbage dies slowly with a sad why? why?. The brassicacea, in other words, behaves very much as you or I would behave if we were a cabbage disfigured after a thousand years of culture and plunged into boiling water after being chopped in a thousand parts (with the obvious exception of not screaming)."
