> I think that - unlike many gyms and other fitness communities - it's very welcoming to non-conformistist and people who don't look like typical gym junkies.

You know, people say this a lot about "typical" weight lifting focused gyms, but I've found nothing but the opposite. There are certainly some people who are in there that are judgy (the are everywhere) but the vast majority are either there to do their workouts and leave, or are very friendly. And I've done most of my training in gyms in Manhattan and Paris, two places not known for friendly people.
