...that the conventional wisdom that young adults tend to be liberal and their elders conservative doesn't necessarily play out that way ("Why Young Women Are More Conservative," reprinted in Outrageous Acts and Everyday Rebellions). In fact I was more conservative in my teens and early 20s. With exposure to different cultures and ideas, my perspective changed.
One thing that does bother me is that it's still culturally acceptable, at least in the media, to marginalize and denigrate older adults. I've even seen it done by older adults themselves (David Broder, call your damn office). If anything, we all need to explore different perspectives, especially those produced by decades of experience.
