Yes and no. There are definitely places where genre divisions work like this: the neo-rave bangfacery/hardcore-as-is/drum'n'bass triple point immediately springs to mind. Massive overlap in sound between the three, but a v.big difference in the attitude of the punters (and DJs for the matter). But then you have social scenes which encompass several musically distinguishable genres. For example, in 96/97/98 most London acid techno, psy trance and hard house nights had exactly the same crowds going to all of them.
Psy trance is an interesting case here, in that I wd estimate that nowadays 80%+ of psy-ppl have no interest in any other dance music whatsoever, which IME of ppl-who-like-dance is rly rly odd. It seems to operate in its own little insular hippy groove. It's a bit of a shame, cos I wd like to see some of its values infecting other genres, not least the seemingly compulsory provision of cups of tea at psy venues.
