Your last point seems especially important/helpful - I do think I would find value in in-person relationships with other folks on a esoteric spiritual paths, but maybe I ought to widen my net and not only consider "heathen" groups. So far, Ecosophia has been extremely helpful, and the regular commenters have shown me that you can get plenty of helpful advice and good sense from esoteric Christians, Muslims, traditional Occultists, Greco-Roman pagans, and so forth.

I suppose the trouble I've had so far is that it seems hard to find the balance that Ecosophia has - folks from all traditions are welcome, but please bring a certain amount of seriousness about your practice. Out in the world, there seem to be two main poles, at least at the moment: the "big tent" Neopagan movement that seeks to include anybody and everybody who isn't a monotheist, which has many of the problems JMG has laid out, and then those groups that have reacted to that by fencing off a particular territory and saying "no, we're not anything-goes, thank you very much, we do things this way". I think a lot of heathen groups have gone the latter way, which risks turning into the "one-true-wayism" you and others have talked about in this comment thread.

Maybe I'll just have to take JMG's advice and start my own Esoteric Reading Library to attract the kind of odd ducks I'm looking for :)
