I would say your simply wrong.
It is not more moral to keep billions of animals alive, and in miserable conditions, solely for the purpose of consuming them, despite any romanticized idea of keeping a completely artificially selected species around.
And also, that there isn’t a world where we completely give up meat eating anyways, and even less of a world where we let them go extinct.
I think the better solution is to simply set up a filter for the word “Unsubscribe”.
