Pickman's model
Starry Wisdom
or that it's just tosh, i can think of lots of people born from say 1963-1977 who are and have been politically active for many years.I've read some chat recently about how Generation X is much less represented in radical political campaigns than the generations either side: I think part of that is due to childcare and suchlike, but there's also got to be another aspect too - that Gen X came up through the eras of blair and TINA technocratic governance and there was no fight for them to join.
no fight during the blair years? i think i missed that email.
