The OP pickleballers do seem to be drawing attention to themselves lately, but I am not sure there are any/many truly altruistic people stepping up at board meetings to raise issues that aren't at least somewhat self-serving.  Perhaps the recent pickleball issues are on the more blatantly self-serving end of the spectrum though.

I get the impression that you give everyone their due, but I'm less sure that you spend as much time assailing the very notion of other group's interests like you have with pickleball. 

FWIW, I play pickleball on a regular basis, but only occasionally at OP.  I've seen many pickleballers get way too carried away about all sorts of things, but I think that is just people being people.  I suspect it just seems more common with pickleball because it results in many different people mixing together and interacting many times a week.  That can be a good thing and a bad thing.  I'd like pickleball more if it wasn't for all of the competitive and interpersonal BS that often comes along with it.  The gossiping and infighting sometimes reminds me of middle and high school.  Plus, many players seemed to have failed kindergarten when it comes to basic things like sharing the court and playing nice.  As I said though, that's a people issue, not a pickleball issue.
