why is the art community so…mean?

it doesnt matter where you go. tiktok, reddit, instagram, etc. no matter how skilled you are, theres always people who are harassing you for not being da vinci incarnate. every time i post my art, people always say mean things. one time, a guy made 30 COMMENTS nitpicking and making fun of my art/artstyle when i never even asked for criticism. do people not realize how disheartening it is?? now i feel like whatever i draw is ugly. no matter how much experience i am, no matter how initially proud i am of the drawing, its never enough for people. people harass beginners off of the internet instead of encouraging them, and i really, really am sick of how hateful our community is.
