Ok fine, he's making his body an object of public consumption, and in so doing implicitly invites people to comment on and judge his physical appearance. Sure. If that's the standard you want to follow, then we are also free to say that the people publicly criticizing his body are human garbage and their opinions are worthless. I hope he finds peace and happiness offline and grounds his self worth (and income) in something stronger than the meaningless opinions of thousands of anonymous strangers.
We don't know what it does to the developing and vulnerable brain of an adolescent who finds "fame" and 1+ million followers on image-forward platforms like IG and YouTube but it can't be anything good. It looks like regulators aren't going to step in to disrupt this f*cked up social media landscape any time soon but for now we can choose on a personal, individual level to not add more sh*t to the cesspool.
