Actually, I do understand it. Therianthropy in its current form considers species to be something like gender, a social role that is detached from one's physical appearance. To them, "being an animal" doesn't refer to their body and mind being that of an animal, but rather it's an aesthetic. It's their presentation on the internet and their lifestyle IRL, possibly wearing a tail or ears, chatting with others in VR as animals, and so on. In that context, the message of these images makes sense.
I just wish people didn't forget about those like me who don't subscribe to this understanding. It's not like I'm doing this by choice, you know?
