Pretty much every club I've been in that gets large or formal enough to have a constitution and elected committee is like this. And even though it may be only one dick stirring things up, it splits the general membership in to 2 factions.
With us it got the the point we said sod it, and all quit the committee, knowing full well that there'll never be contested elections (there's alway N people standing for N or N+1 places), so we have about 50% "friendly" people on the committee. We also knew that the dick would either totally screw up the club, or do absolutely booger all. We remain members solely to be able to call an EGM. Fortunately, so far, he's done booger all, just like pretty much everyone else that complained about committee not doing anything.
One day, it will be EGM or mass defection and create a new club.
And any club I ever help create will only ever be "a social group of people with a common interest".
