It's understandable that not everyone would "get" the concept of a fursona, since it's a very idiosyncratic thing. Hell, within the fandom itself, there are *so* many layers to the concept.
Some people identify as furry, but don't have a "fursona" per say, they just "like wolves".
Some people have a fursona, which is just a very loose alter-ego or cypher, for fun.
Some people have a solid fursona, meticulously designed, that they love to show off.
Some people think they were a duck in a previous life. And who are we to judge?
Some people have an entire roster of fursonas, literally hundreds, and wear whichever one they want at that moment.
Some people actually *buy* popular fursonas, usually tied to specific fursuits, so they can *be* that "character", kind of like sliding into a role.
Some people are dragons, and you just don't understand.
Some people were raised by a family of wild badgers, or 80s cartoons, and are now badgers.
Some people just want to be more, or different, from what humanity and reality insists they are.
So, YMMV of course - but it's fascinating really. Talk to a thousand furries, get a thousand impressions on what furry, and fursona, actually is.
