The Pit is a cesspool but it comes with a warning label even though seeing some of the responses makes you wonder if it's worthwhile to even be here occasionally. A previous poster saying maybe the Pit should go away may be onto something actually but it is what it is.
I think there is a difference between banning someone, just tuning them out, or hearing them out as they speak their mind. I live by a rule of thumb if someone is just outright lying or willing to engage in the conspiracy theory thinking such as a Tucker Carlson who in McDougal vs Fox News his own employer said no reasonable person should believe him...or by his own admission "i'll just lie" they should be banned. Throwing in Alex Jones on this too as even he has argued in court no reasonable person should believe him...allowing them to continue is harmful as it's dangerous to public discourse/information.
Tuning people out (like I've done that to a poster on this board because it's nothing conspiracy theories and 7D chess about why the last conspiracy theory didn't work out with a new conspiracy theory) is okay because sometimes people are not overall a detriment to society just putting the "you're ignoring this user" works.
While letting people who operate in good faith are fine to hear from with different opinions, like how to run a government which is totally in bounds to be heard even if it is something you disagree with, Supply Side vs FDR Tax policy, putting out prevailing and consensus historical records totally fair as sometimes historically what looked good at the time (Woodrow Wilson vs Harry Truman for example) Wilson was widely popular during his presidency but as time went on not so much, and the inverse like Harry Truman who not popular at the time but historically looks like one of the better Presidents the US has ever had as he established the Post WW2 order, hearing new evidence is necessary when it's available regardless of what side of the aisle it comes from. ( Though huge disclaimer here ONLY if it's in good faith obviously if someone is just willing to lie, outright whataboutism, or do the dreaded Both Sides despite the evidence they fall into the Tune Out/Ban part of the spectrum) .
