You seem to be reading a very different site to me.
New posters often turn up, ahgast that GC perspectives that they are unused to seeing in other contexts due to (online) heavy moderation/bans, and (offline) the chilling effect of heavily pro-GC diversity policies in work and media are allowed to stand, and challenge the GC position using what they believe are the unassailable arguments they have seen elsewhere.
They are shocked to discover that not only are these arguments not in fact unassailable but in fact rest on weak logic and/or inaccurate information, but they have been raised, discussed, challanged and dissected many many times before (something the crusading new posters would know had they the basic online ettiquette to do a few searches, or today even ask a GPT for a precis of what has been previously said on the topic), to the degree that FWR regulars have evolved a literal playbook for answers to the same old arguments.
At this point, one of four things will happen:
They listen, stay around, evolve their arguements and understanding. They may move to a more GC position, they may not, but either way they take what other posters are saying on board. This is good faith.
They disappear in horror, never to come back. Also good faith.
They disappear from FWR most of the time, but pop up on threads like this and general MN "what don't you like about MN?" type threads to complain about FWR pile ons and how they were bullied off for not toeing some FWR party line (as opposed to the reality that they simply had nothing new to bring beyond already debunked claims and emotional manipulations that have just stopped working). This is - questionable faith. On balance I think they do believe their hype, but manipulative people often do, and it does have the I'm sure unintentional advantage that anyone who says "No, it wasn't quite like that" can immediately be used as proof of just how bullying FWR is. A catch 22 - if you say nothing the lie stands, and if you say something, it just proves the lie.
They engage with the counter arguments on the thread, yes simply disputing rather than learning but neverthess acknowledging those posts have been read, but then pop up with exactly the same claims and the same "facts" on the next thread and the next and the next, all wide eyed as if they had never come across any differing positions or had the "facts" challenged and debunked. This is not good faith.
I will engage with the latter group (I know many FWR regulars will not), not because I think there is any hope that they are anything other bad faith posters, but because I think it's important that other readers who may not be aware that this is a groundhog day poster are given the full picture by either referring back to the times this topic has been discussed with the same poster at length, or by referring to a thread covering the same ground with a different poster and suggesting the new poster reads it first then comes back with an argument that progresses from what's already been said rather than simply restarts it.
The board is moderated fairly. The fact that GI arguments are weak is not a moderation issue.
