This comment chain is you defending PETA having high euthanasia statistics due to euthanizing animals they had taken from families yards and from homeless individuals. You had suggested that these euthanasias were mercy killings, and when another commenter pointed out that pets can’t be considered suffering even under the loosest definition of the word, you posed a rhetorical question in bad faith. If you actually wanted to argue that PETA’s euthanasias are only done in situations of suffering animals, you would have just said that and perhaps included a source for that claim like the initial commenter did for theirs.
