Helping people with questions does not in itself prevent them from being democratic. Nor does it foster this. These are separate issues. The administrators could have chosen to operate as I do on my own website, where only I can answer questions. They chose to allow others to answer questions. That doesn't mean that they have to subject themselves to the will of those others.
If I allow somebody into my house, that doesn't mean that I have to listen to them when they tell me how to bring up my children. I can throw them out of my house whenever I please.
And the administrators of this forum can throw us out (by banning us) any time they please. It is not our forum - it belongs to them. The fact that they have chosen to tolerate some us frisking around here does not change that.
