I say this because one of the biggest problems of every single group or organization that I've seen built around progressive/left/liberal ideas is the tendency to believe in the "everyone has a right to be heard/speak" which leads to everything being dominated by the loudest individuals who are almost always full of BS.
Honestly, I've identified this tendency as the #1 reason why such groups do so poorly in politics, except in situations where the values are just a PR front for a more traditional power structure.
