SL Discussions: One Man Show?

Let me start with what a non-English speaker like me defines as a discussion:
 "dis•cus•sion (dɪˈskʌʃ ən)  n.
an act or instance of discussing; consideration or examination by argument, comment, etc.; informal debate." 
(Yep, right from the schoolbooks!)
I am in a few philosophy groups in Second Life, where from time to time if an interesting item pops up in my timezone, I will go and listen. Just listen while I browse the interwebs as most of these discussions are held in voice.
And today: 
[07:58] Julie: revolutionary new discussion meeting for any of oyu deep thinkers out there who want to talk about life, im me for a TP

How can one resist, right?
Usually I read the inviter's profile swiftly but this time I did not. Once there the revolutionary conversation was briefly about dead to go on to dreaming.
Where the host-typer claimed to have deep conversations with people in his dreams which led to him ask us what we think of these people: 
Julie: 1. your own subconscious mind
Julie: 2. another person
Julie: 3. another entity or something
Julie: 4. or all of them or mix of them
I answered that he was talking to different parts of his own personality (based on what a few psychiatrists wrote on this subject and so for myself a reasonable explanation). Offended!
"Are you stating a fact?"
He then got quickly upset telling me I am a mold and not creative or authentic as I come with other people's opinion because I am not able to have my own opinion. Followed by fuk scientists. 
The people in his dreams are real.

I left the discussion to avoid drama.
Back at my own place I read his profile and was kind of overwhelmed by the amount of delusion. 
If I had read it before I would have seen it coming. 
Some keywords: bipolar, unique awesomeness, transgender, sensitive, deep as the ocean.
Some of his groups: God-fearing Christians, Church of Satan, Mental Illness Support Group, Suicide Pact, Depression Support Group, Yes I am a T-Girl, Borderline Personality Disorder, UFO Stories and a lot more. Duh.

And it kind of struck me, many discussions in Second Life are held not to have a discussion per se but to be the center piece of attention, to fulfill that need to be seen and heard. No matter what the subject is about, no matter how authoritative the host speaker about the subject, one should just nod and agree. I have experienced this on many occasions at the Gateway, the walhalla of the bdsm discussion. Do not talk back/type unless to confirm what the speaker said preferably with an example of your own experience to beef up his/her statement. 
There are of course some brilliant speakers in Second Life, and I have witnessed several nice discussions. As they say in my language: "the exception makes the rule" (doesn't make sense to you, I guess :P)
In the following weeks I am gonna visit more discussions round and about to test this. I let you know the results in detail with some chats to read. :) 
If you want to join the dommelette on this quest, drop me a line in world.
