Forums are made for discussion. Having people leave because you/they disagree would be absolutely pointless.
Maybe at this point it would be better to shut down the forums. People can't agree politely and it seems like many have taken things to the extremes. We have people brigading with their private discords, small armies of alts doing the same.
Even without all of that, it's very rare to see people on here trying to find a compromise. People treat discussions like wars to the point where they're willing to outright lie to "win".
