I don't think there's anything wrong with the existence of private events.
Neither do I. Their
existence makes perfect sense: I don't invite everybody I know to every dinner or cocktail party I host, either – I invite people who know each other and have things in common. My only objection is to the dishonesty of
saying, "You aren't sufficiently high level," while
meaning, "You don't dance like we do." The former sounds judgmental; the latter, objective (I'm not invited to, say, football parties because I don't follow football, nor to my partner's workplace Teams meetings because I don't work there).
I also don't think it really has anything to do with skill level.
Precisely.
People have a very strong tendency to conflate whatever they personally value with some sort of "objective" level (which in reality does not exist.) I am not immune to that myself.
For sure!
I dislike what I call the "El Mundial" style that's prevalent around here: very tall "salon" tango with torsos barely or not touching, and consequently minimal axis- or weight-sharing, plus extensive step projection and large turns that orbit back along the line of dance, all led in two dimensions (the plane of the dance floor). I prefer more knee bend, a tighter hug, (non-illusionary) apilado, smaller steps, and turns that progress forward along the line of dance, all led with a major vertical component (i.e., strong suspensions and groundings).
When I see what I like, I have to consciously tell myself not to identify it as "higher level" than what I don't like. When I see what I don't like, I have to consciously tell myself not to identify it as "lower level" than what I do like. I know I'm picky and I try to be mindful of the fact that it's a preference, not a question of skill.
Still, were I inviting people to a private event, I'd invite people who dance more like I do. I'd just have to force myself not to couch things in terms of "level."
