Actual question here: How would you deal with this situation if you were B-Dubs / the mod team?
Doesn't seem like there's any winning play at this point.
There is no way to deal with it, they can't reign in the monster that they have made.
I would tell people that we are here to have civil open discussions where everyone is equal, and each community has their own thread to take other matters.
If Transera wants to make a thread for the evil of cdprojekt red more power to them, it would not be sticky and would be dealt with the same respect as other threads. If people go in and troll they will be dealt with but the same goes the other way if they go into other threads and troll the same thing.
If the thread drops or floats it will be on the merit of the thread. This goes for all social groups, this goes for all topics.
If a game has racist tones, make a thread to discuss it and again it will be dealt with in a civil manner and respect and trolls will be dealt with but if you take it into other threads in a heated manner than you will be dealt with also.
This is how it should be.
The knee jerk label jobs are as toxic as it gets, and even now you see it in recent bannings. They have terms and labels for everything so that they can handwave discussion.
You have the one person flipping out because they were called out for trans erasing, and lets be clear they were very much doing that. Other people would not be in a position to complain because they would be perm banned.
