You’re touching on a huge topic, and I can’t do it justice, but the simplified answer is that blocking voices “fairly” is nearly impossible. If you choose to block some voices, you inevitably have to draw a line regarding what is allowable versus not. But voices don’t exist on a one-dimensional spectrum where you can simply block everything to one side. Someone has to decide what is allowable, but who gets to decide that? Who decides who gets to decide? Regardless of whoever ends up becoming the decision maker, reasonable people will disagree, creating more conflict.
