You're absolutely right here, wanting to be an animal is the core of it. It's all the things therians and otherkin build around it that I don't identify with and which makes me hesitant to adopt these terms for myself.
Here's a different scenario to get my point across better:
Let's say I'm interested computer hardware and how it works. In this scenario, therians are people who're into software development and otherkin are PC builders (both chosen arbitrarily so this isn't a value statement). At the core of both is still computer hardware, but what they're doing with it isn't necessarily what it means to me. Maybe I'm more interested in the physical mechanisms or the theoretical foundation.
I'm leaving out a lot of detail here. You could, for instance, point out that therianthropy has become way less strict in recent years which should allow me to feel welcome unlike before. I plan to talk about all this in a separate post.
