I suppose my opinion is like most but I wanna yap about this so bear with me XD
I do quadrobics, but I don't do it as a form of self-expression or to "feel closer to my theriotypes" It's rather dysphoric for me if I were to do it like that because obviously the human body isn't built to run on all fours, it's uncomfortable to pretend to do it as if I were an animal if you get what I mean.
BUT I do practice it out of pure fun, I used to do it as a kid not knowing what it really was (kind of confusing, but this past experience does correlate to therianthropy, I suppose it's because I had no other way to "show" that didn't feel fully human since I had no idea what was happening and stuff lol) which gave me a kind of advantage when I did realize that quads existed and when I started to practice it, it's a good exercise after all and its silly too :3
Posting quadrobics on social media isn't necessarily wrong and I'm thinking of doing it too, even if it is a little cringe lol, but the main problem is that people think that quadrobics (and masks but not the main thing) automatically
makes you a therian or that you have to do it to be a "proper" therian, which is obviously not the case, and no matter how many videos we can make trying to explain this to people (or even trying to teach haters) we will never be able to fully reach this out to everyone.
(okay don't get me wrong tho but its def be fun to do quads at a trampoline park, just to make the 9 yr skibidi toilet kids mad XD)
feel free to add anything
