I think the elephant in the room at the moment is definitely posting styles, and it's not exactly an easy issue to address -- either in a non-flamey manner by other posters, or in a logical regulatory manner as a mod. Obviously every poster has the freedom to post in whatever way they feel gets their message across best (I mean, my method of "dodgy analogy, dodgy pop culture reference, hashtag" isn't exactly widely-used), and those differences are integral to actually having vibrant discussion and not ending up becoming too much of a circlejerk where everyone holds one opinion and spends their time writing posts of agreement about everything.
As mods, we don't want to silence debate or cut out robust discussion on issues in order to enact a 'party line', so to speak (and I admit I have been heavy handed on this on occasion -- e.g. my "ffs dont compare gay people to pedophiles" post in that particular thread which left itself open to serious misinterpretation). But at the same time, that robust discussion turning into massive flamewars and ****fights waged on personal grounds.
I think a lot of the issue is people being unable to agree to disagree -- in the NZ/PAK thread we've seen plenty of disagreements over selection, player ability, and various team comparisons where neither side is willing to cede any ground to the other. Foruming isn't a zero-sum game where one person has to 'lose' the argument for the other to 'win' on behalf of their opinion. That's argument, not discussion or debate. Then, when it's gone around and around in circles for three or four pages, it's only a matter of time before someone makes it personal, and it goes around for another four or five cycles, only this time with personal abuse.
Then every time the posters disagree in future, the number of cycles before it becomes personal shrinks, and the problem gets worse and worse. I genuinely hope we've reached Peak Flamey Arguing in this tour thread, and that we can reset the problem and not degenerate to this level again.
There needs to come a point where both sides are willing to accept that they aren't converting all and sundry to their viewpoint. And even if they did, how boring would the forum be?
"Player X sucks so much, shouldn't be picked."
"Yeah I agree entirely, he sucks and shouldn't be picked."
"Erm, look how hard he sucks."
