I agree with you. Also an observation (not positive or negative in any way) a lot of the younger people I see under 20 persay are seemingly very quiet and reserved, that might be just a social thing and they are much more outgoing in other situations. I've heard that drinking alcohol is also much lower, so if you have quite a few people that don't feel comfortable dancing, are more used to being social online, and drink less then I would assume that dancing might be a little more rare. I think op might just have been in a bit of a bubble growing up where culturally it's was more open to dancing.
