I don’t think either is acceptable. But other animals have to accept it from us, and we would have to accept it from the aliens. Ultimately it would be up to aliens to determine what happens because they hold all the power, just as if other animals are ever going to achieve liberation it will be because of humans changing, not themselves, which is unfortunate.
But other people might make similar incorrect comments, better that your comment with the reply that makes a correction float to the top (for people who sort by upvotes). The best solution is probably editing if you have the time and upvoting the reply. Similarly I’ll upvote something incorrect if I reply to it but downvote if I don’t have the time to reply.
