I'm baffled ear cropping/tail docking still exists (banned in many places but still). Cat de-clawing too to a lesser degree but at least that has something of a practical reason even if it's a lazy one (though if you're so worried about it scratching things give it toys or just don't get a cat). But the former is 100% cosmetic and serves no genuine purpose.
One of the endless reasons why I have a hatred for the concept of "fashion." Looks over everything else, no matter how nonsensical, unethical or downright cruel.
