Wow! Your repeated, willful mischaracterization of other positions is intense. Where in this thread have I, @AlViking, @Lanefan or @Necropolitan said that the GM should willfully ignore the group and be a domineering, spiteful a-hole?
You've continually misconstrued "having a clear leader" with "being a petty tyrant." At this point I have to assume you aren't discussing in good faith.
It's a common theme that's gets repeatedly introduced even in threads that have nothing to do with GM authority.
