BD comment of the day: The second act of the Doonesbury character BD

I was struck by this observation
by "JESTEPHENS" about the BD character in Doonesbury: "If only we all
were as reflective as BD has become. Remember in the early days of the strip
how emptyheaded and reactionary he was. Trudeau has taken BD from that
shallowness to a character who has become something of a cultural barometer."

This is one of those things that seems obvious when you read
it -- but it had never occurred to me. BD is now one of the major heroes of the
strip.
