Trying to classify generations like this is dumb. I mean, depending on what cutoffs you use, I am apparently supposed to identify more with people 10 years older than me than people a few years younger than me.
Part of the problem here is that societal attitudes evolve at a much faster rate these days, such that 20-year generations are not really a useful sociological concept. I already see a pretty significant difference in attitudes and outlook between my peers and people just five years younger than me.
