Xe Iaso here, thank you for your kind words. It really means a lot. A lot of the time we just fire things on the blog out into the darkness and it can feel like we get nothing back. ^^
Reactions like the GP are why we prefer to be more tactical about plurality in public. We've found it's better to be seen as an expert in your field AND THEN be more safe with talking about plurality topics than it is to be a vocal example of being plural and then having to fight uphill to be seen as an expert in things. Stigma is a bitch and a half to deal with.
We'd like to think that our writing and advocacy helps destignatize our form of existence in some way, but we have no way to track that other than the occasional kind comment. Maybe this job will be the one where we are more honest and open about plurality, but we've also found that it's an ultimate relationship strength test like coming out as transgender to people (I'm pretty sure it's why my brother refuses to talk to me). We don't want to lose more people, so we have defaulted to this quietly, but accurately describing how we experience reality thing and not emphasizing it too much. The blog is a team effort ;)
Interestingly enough, I've found that plural people tend to understand distributed systems problems at a much more intuitive level than others. It's to the point that if I was ever building out an SRE team to handle distributed systems problems, I'd probably try and hire as many plural people as I can and make them accommodated to the best of my ability so that we can leverage that innate talent in ways that were previously undoable. Maybe some day I'll get my wish, but not any time soon it seems.
Personally I'd say that otherkin and furry have overlaps but are not fundamentally the same thing. Think of it as the difference between being a fan of baseball games and aspiring to be a baseball player. They are in similar veins (both baseball related), but they are wholly separate things. Being furry and being otherkin are similarly different. I can ask around for a resource if you want, if you want to reach out privately please email me at xeiaso dot net.
I'd second the suggestion to avoid hate groups like /r/systemscringe, nothing good can come of it but continuing the cycle of needless hate. I'd like to think that people on this website are rational and can overcome the innate tribalistic feelings that those hate groups capitalize on, but I can wish in one hand and spit in the other then see which one fills up faster.
"Furries run the internets", and as a result the tech side of the furry fandom gives you a vast professional networking opportunity that you could never really get anywhere else. It makes fiscal sense to be a furry if you value having a large professional reach.
