Complete transparency, honesty and communication with EVERY member is the only way something like this can be successful and maintain support. It’s difficult to implement securely, but 100% worth it for the longer term.

An inability to find common ground or compromise, can have a very acute viral effect within any organisation. It can be equally mirrored on the other side of a divide when parties begin to see heels digging in.
What you then have, is a cultural issue that can only change with new personnel, mass culture change or people being able to accept their weaknesses and/or limitations and stepping down.
Do you honestly see any of these changes happening in the short to medium term?
