>>I don't mind averting my eyes as long as it's not to avoid a something physical aimed into them, like a pushy ringer or a greeting which is for members only or just having to explain etc. Religion is a personal matter, and I have no intention of meddling in other people's personal affairs. On the commons, OTOH, it's always a bit unpleasant to be forced to observe personal lives of others, feels out of place. Just like watching a marital fight in the street... may be interesting, but you don't really want to watch.

>You cannot control what others think, so it isn't worth worrying about them. And I have enough trouble running my own life, so I won't be trying to run theirs. I don't care what group puts up a display for whatever event is happening in their lives. Public land is okay AFAIC.

It's possible to do it in an unobtrusive way, which they rarely do. Usually it's as if they assume everyone is a member, do it in-your-face (i.e. coming too close, putting their stuff so you have to go around it etc). Can't they do it at home?
