It really depends on the argument.
The bandwagon fallacy is if just because someone else is doing something does not make it moral. It seems like the parent post was saying that the moral rules only apply to humans.
It seems they are claiming that all animals are people, that killing animals is as bad as killing humans, and humans deserve to hunted for killing animals.
This naturally raises the question of the morality of other sentient animals killing animals, and what they deserve.
Perhaps all predators are evil and should be exterminated
