i do it and i see nothing wrong with anyone doing it itself, it's just that a lot of young kids think that doing quadrobics makes them a therian, and lots of those people are probably not really therians, just confused kids who are furries maybe. of course, you can be a therian at that age and do quadrobics in a mask on tiktok, and it doesn't hurt anyone if they do it, as long as we can inform them on what therians really are so that non-therian ones don't falsely claim to be a therian. even if they aren't therians they are welcome to do that still, its just some harmless fun and anyone can do quadrobics if they want
