Well quite.
Like it or not Mr. Tea, I'm a council estate boy whose mother felt forced to try and get me into the local independent school on a scholarship because the local high school was so shitty. I believe I was the first kid from my primary school to do that, despite the independent school being only 2 miles away.
I never said that all jam-makers are middle-class anymore than all people who go to yoga are middle-class. I do kinda concede your point regarding 'ecstatic dance sessions' - in a sense exploring that arena was an interesting mistake. An interesting period of discovery, not least discovering the bourgeois underpinnings of such scenes. But getting people to stretch their bodies, jump around a bit and maybe dance around a bit too doesn't have to be woefully middle-class and I'm not convinced 'devotionality' has to necessarily entail fluffed-up middle-class fascism.
Working class men tease and banter with women all the time. I don't tend to think 'negging' is a good thing to try to actively learn to do, but......whatever really. If you think it's some kind of big deal, then by all means think that. Authenticity is not a sacred cow for me.
