I am their age; all my friends are that age; not ONE person I know have anything close to their value system!
I'm about the same age too -- more useful to adopt the distinction (Tyrrell's) between the coat-and-tie radicals, who protested Vietnam, etc., etc. but not to the extent it would ruin their "political viability", and (I think) the penny-loafer conservatives; he sees these battle lines drawn in the 60s, 70s as continuing -- and strengthening into the present.
Boomers as a group and as a type are not conservative, not in the sense that we refer to them in this culture.
