alt Hacker Newsyou know that people really go there to dance and enjoy the music?
A friend of mine is a professional (modern) dancer, so has as much credentials as you can, and she enjoys dancing in berlins nightlife. She finds the space for expression and creativity in her movement, in tune with the music. Of course, the is not much physical space, which is how the dance-movements evolved as they have (e.g you never spin and you feet never really leave the space they are on). But this is part of the culture, and not a problem. If you can't find it then that's your problem, but doesn't mean that other's can not freely express themselves there.
There's more dance-events. Not sure where you are, but you can usually go to a bachata night as it's quite trendy now, northern soul is also getting some revivial. There's also more disco-oriented events usually at various LGBTQ+-parties, I think especially italo-disco is a lot of fun. You can just go out and dance. Lindy Hop also has a solid community around the world.
Thanks - yes I'm aware of most of those (my handle here is a northern soul record) and do attend but they are relatively niche and I resent the current way mainstream dance music events are presented to the world as something that seems counter to the notion.
Btw I've seen great dancers who barely move their feet; my concern is with the culture where individual expression is subordinated to the cult of commune and the DJ.
As others here have pointed out that is partly down to the promoters packing in as many people as they can; I think control moving over the years from love of the form to strictly commerce has caused a significant change in culture.
