There are three different circumstances.
1. Established MO communities that are a part of major Jewish populations. This is being debated.
2. Isolated MO cities. The observance there is largely at the mercy of the abilities and circumstance of some rabbi many years ago.
3. Communities that are not established and only serve as a place for Jewish Adults to have a communal lifestyle. These communities are made up of whichever Jews decided to live there at the moment. They have little continuity. And less oversight. This is not part of the debate. It is Barely Orthodox. BO not MO. The young people there come from all over including Williamsburg and Lakewood.
