You would need an anti-nihilist group for any sort of "utopian" stuff. Things are as they are - reality is as it is and works the way it works regardless of what one thinks about it or whether one likes it or not.

I like reality and there are others who also like reality which is sort of like a "group" except we all have our own interests and, so, despite the fact that we can hookup without missing a beat, even after a decade or more, we are spread out all over the world and don't "hang out" together. We're not a physical community or any sort of social "group". We just share a profound interest in and respect for reality and enjoy the occasional dialogue about the things we've discovered. We also share a complete lack of interest in what you seem to be looking for - on the other hand, close encounters with such "groups" often spark dialogue between us.

You're not going to find a "group" that shares your every bias. Those are your "meanings" and every "meaning" is, by definition, different. As near as I can tell, the only unshakable relationship is between those without "meanings" - without biases - those who share a profound peace with reality.
