The “transfur” aspect of Changed is as much an aesthetic conceit as having the Experiment be an anthro. Changed uses that to tell a story — yes, it is indulgent, it is sexual — but it's still a piece of art.
Thing is, the furry community is built on weird. “Cartoon animals in more serious contexts” that's weird, why not do it with humans? What do you mean you make art of yourself as an animal? You can't un-weird furries by removing specific aspects. The fandom is breeding grounds (heh) for weird people because when everyone's weird, being more weird isn't a problem.
The way to make being furry not weird is to normalise it. The more people make bad sketches of themselves and publish them, the less weird it gets. The more people play dress up or roleplay online, the less weird it gets. The more people publish media containing, and talk about niche or off-putting kinks (in the right spaces), the less weird it gets.
Just like how gay people and mental disorders are getting more accepted due to exposure and media that talks about it, so would furries and accompanying weird stuff at some point. Now, being furry is a choice. You're intentionally declaring yourself as weird — as an aesthetic goal, but also to build community. Nobody should stop you from having safe fun, from being yourself.
Furries in other media haven't been portrayed in the most favourable light, leading to a lot of people having a false impression of what furries are. I feel like it's been getting better in recent times, but it's still an issue; the most that you can do to help is inform people.
If someone dismisses something because it's “weird”, that's their loss. I agree that it's disappointing how many people dismiss content they may like due to trivial stuff like it being furry, but that is at no fault to the fandom itself.
Thank you for reading what (accidentally) turned into an essay, and stay weird everyfur!
