I think he's more than permitted to post anywhere he pleases
It's not a question where he is permitted to post, I never questioned this, but I am asking why he is posting in a subforum dedicated to a theory he clearly does not seem to believe in and thinks is bullshit and the one post he did post was to simply express this sentiment.
With that being the background, I think I have a good reason to question why he chose to make that one post.
Btw, look at the opening post That's inspiring. Anyways, I do care about all the typology systems that seem at least 51% accurate - and it certainly includes enneagram.
BTW, I didn't joke about the OP. I feel this mad stupid intensity sometimes, the opposite of being carefree or anything like that. So yeah, there's certainly a connection between an 8wX or Yw8 enneagram result and being intense.
Edit: I think some (but not all) very un-8 people feel these maddening intense moments as well. Actually, I feel as if most the mad people I've encountered lately have been very un-8 in their behavior.
