As of now PvPers are actively self-segregating themselves from the official forum entirely. I would think that a dedicated sub-forum for PvP for all to see next to all the other established sub-forums would be an acknowledgement by FD.
But as per the poll, PvPers are apparently so conflicted that they don't want the acknowledgement... [where is it] I conclude that it's inherent in many PvPers DNA.

Maybe "established" doesn't sit well with the PvP identity?
Well that's a pretty naive conclusion to make if the depth of your research is one thread and a Discord interaction. To assume you have correctly mapped PvPers very DNA is wishful thinking at best if that's the extent of your research and examination on the matter.
A whole heap of separate conclusions could have been drawn from that thread depending on what you bring with you. You drew 2 conclusions, I offered 2 more conclusions, other people could draw yet more conclusions based on their own interpretations. That's not really a definitive piece of research there from which to draw any significantly meaningful and accurate conclusions now is it?
How many people that voted in that poll were PvP players?
How many were PvE players?
You didn't expressly ask for PvPers only to vote and comment so how can you come to the conclusion that PvPers are actively self-segregating from just that? By my reading through that thread it seemed quite a few PvEers were also wary of creating a seperate PvP subforum, why would that be?
You didn't cross examine the other things that were brought to the table such as the history of why PvPers feel that a mass exodus from the official forums was an action they felt they eventually needed to take or why PvPers feel a lack of representation in the moderation of this forum. What empirical evidence is there to either support or deny the claims of harsher treatment from the moderators towards PvP-centric posters for example?
Is there a causality factor to the feeling of persecution coming from PvPers on here? Was it indeed a snowball effect that gradually eroded the goodwill between PvPers and this forum or is it driven by the continued feeding of a myth on the PvPers end? What was it like to be a PvPer when the game was still in Beta or just newly released? What were the feelings and attitudes on the forum then compared to how they are now? And why?
These are the things you need to ask and provide an answer to in order to back up an assertion as concrete sounding as 'It's in their DNA to be anti-establishment'.
I can for example immediately disprove your theory that PvPers are actively seeking to self-segregate themselves from this forum by posting a link to this thread here:
