it's a specifically built space where there's no bullshit, no mucking around, no jokes and no games.
The fact one that acknowledge what you call, or could get to called on one's -->bullshit<-- is part of the growing, Accepting and coming into terms about "demons" or "our faults" is when we start to be free.
When we smell something is bad and we discover it's our own bullshit, then is when we discover that we are wrong.
Why no jokes?
Fucking life is a joke is full of ironies, laughable times, dramatic moments, sweet moments, bitter ones; a true friggin mess, and it's beautiful and wonderful as it is. Certainty and uncertainty? Don't you consider a group of man talking about ALL moments considered to be a joke in itself, specially the ones that in the moment we consider and feel "bitter or/and sad" when we revise them later we found them warmingly funny?
If you are talking about the posts in the lounge consider it as it is, a LOUNGE. It's like when you say hi to someone and speak trivialities, you know that person has a deep side you're just not interested in the moment to dig that far, and how awkard that would be like:
Hey hello, wassap! How you d... So what's the thing that you do with passion in your life, Oh and almost forgot...did you cry yesterday?
Everything that is done here serves a purpose. But then maybe not in your opinion.
And thats ok.
