Completely anecdotal... but many years ago I used to help admin on a board very much like this.
In my, again, completely anecdotal, experience, ... kinda sorta yeah.. but as someone 'adjacent' to the gay and furry community, we're not alone.
I won't call it mental problems or mental disorder. I'm no clinician.
But, as far as humans go, there seems to be a lot less 'stability' - at least for the youth - in these communities.
A lot more raw emotions that ... maybe .. don't get fully processed in otherwise socially acceptable ways.
And by 'stability' I mean a number of things: a job, a functional social group, a partner, property, assets, long term goals..
Or, NOT having: issues with addiction, an existing diagnosis, pre-existing trauma
Now, fair disclosure, I would put myself - as many others - into the slightly unstable camp.
That said, I've done two long term career-level stints already in a highly technical field, have been responsible in managerial positions and large financial decisions, own a house, have my own animals, etc. ... but I still smoke weed, I'm still.. 'not the same' as the other people around me .. have odd and specific interests .. tend to get myself in trouble with my honesty and reading of people.. tend to find myself opposed to blind authority .. tend to not go with the herd. ... and 'technically' had a 'syndrome' diagnosis as a kid, which, I kinda think was bunk.
Am I on 'the spectrum' ? .. well... it's a fucking spectrum, so... probably?
Would I consider myself normal? Absolutely not.
For better or worse.
