The most common mental disorder in TA.

Or maybe emotional disorder.

OWD?
Autism?

I think is 'MANIA'. (According to the spanish definition of the word)

manía
Preocupación caprichosa y a veces extravagante por un tema o cosa determinados.

(Whimsical and sometimes extravagant preoccupation with a particular topic or thing)

'preoccupation' and ' extravagant' are the key words.

How many efforts, how many posts and threads, how many fights some people here put/have on a daily basis to prove some 'super important' issue.

Normally how dark or light are these or those and other fascinating derivations of the same theme.

They could spend all eternity discussing their conflicting opinions , and apparently they get deep satisfaccion from that, because that's what they do. (for years.)
And not only some conspicuous members of the hispanic community act like that, I think that people like Oliver1900, Septentrion, Aherne, Tooting and some others are in the same league.

Well, everybody is entitled to do whatever they want with the limited time of our lives, but it's sad, quite sad, to have your mind fully absorved by an 'extravagant preoccupation' during years.

Sanity.

I would love to read the origin stories of members' OWDism and Nordicism.

I would have no interest in judging the OWDism or Nordicism.

Mania, probably what Incal means when he talks about OCD too. "Autists" are a vocal minority.

[Incal]

I'd say, in order of prevalence:

1) OCD (basically a must)

2) Autism spectrum

3) "OWD" (not on the DMS-5 but basically a mix of insecurities/low self steem associated with race and combined with cognitive deficiencies)

4) Narcissism

Well yeah, , not only 'extravagant' but besides obsessive compulsive 'preoccupation'.
I guess there're 'light', 'medium' and 'severe' cases of users affected with mania.

Yes, it could be interesting. But I think nobody will talk about it.

[Colonel Frank Grimes]

High Functioning autism is the root cause of many of the problems.

Collective and individual narcissism perhaps. My tribe is betters than yours, my shit smells yummy and yours dosn't etc

What are the chinese, japanese, arab, south-asian, black african 'manias' about race?.

Maybe they have different topics and 'the lighter the better' is only a white/euro mania.
