The Faces of Scenius

I wonder if it is harder, not easier, on the internet for scenius (of any great magnitude) to form. A related article by Packy says the main blocker to scenius forming on the internet is a common goal strong enough to unite people, but I think this leaves something out: the root of a group embodying scenius seems to be strongly held common values, like those expressed by the initiation ritual of Ben Franklin's Junto, WITH some buffer space for free thinking ("local tolerance for the novelties"). This does not necessarily imply a lack of diversity of thought, just a common foundation, with some space to maneuver without excessive judgement and indignation.

The issue is it is almost politically taboo to demand common values for membership in a group these days, especially if those values are opposed to some mainstream values. It is easy for non-mainstream groups to be discovered and 'cancelled' by reactionary, opposing groups (usually people embodying ressentiment). How do you go about finding people who really share your values and are willing to organize around some common cause as is required for scenius? Second, how do you protect such groups from being destroyed by opposing groups? The more discoverable a group is on the internet, the more direct opposition there will be to it.
