I would never propose that we stop criticism of fandom -- that'd be silly (also I enjoy the occasional critique). But I think it has to be opt-in. In the old style LJ we sort of had this separation between your journal vs various comms and I think discourse in the comms was treated differently (you came there to hear others talk) than it was in your own space. Now that the "space" (whether on Tumblr or Discord) is no longer broken up in private vs public everyone is talking in everyone's face. It's like the difference between me having an opinion in my own home vs showing up at your dinner table and letting you have it. It's hard to figure out how to fix that though, since I don't necessarily want to go back to the days of yore (nor can we).
