I think the more important thing is that it's in public.

If someone shows up and states their grievance and I think they're kinda cuckoo, eh.... I probably support the board in ignoring them.

If someone shows up and has some great points and the board ignores them.... I want to keep that in mind next election.

It really sucks if free speech gets de facto limited to private channels; we lose all the other benefits of it being in public.
