If there is one type of comic that is a prime target for ridicule, it's the DC comics from the seventies with a political message. I haven't actually read the Green Lantern/Green Arrow road trip sequence, though I know it has enjoyed a better reputation than most. But that may be due more to the Neil Adams artwork than the quality of the writing.
Other efforts have not fared so well, particularly the "women's lib" issue of Wonder Woman (#203) and Lois Lane's venture into racial awareness in "I am Curious (Black)" (LL#106).
I don't believe the criticism of this comic is entirely fair. I thought it was an honest effort to address the issue from a time when comics were expected to be light entertainment and political stories were virtually unknown. Not to mention that it was written by Bob Kanigher, an old white guy who was more used to doing stuff about haunted tanks and nonsensical superhero fantasies.
To complain about the clumsy politics in a comic from 1970 is like sneering at the poor quality of the computers in the Apollo space rockets of that period. Sure, today's digital watches have more computing power than the spaceships that went to the Moon, but they were the best available at the time, and they still got there. And look at the clumsiness of the social message in original Star Trek - having men who are half black and half white being prejudist against men who are half white and half black is at least as painful as Lois blacking up for a day, and yet it is hailed for its insight.
Rather than denigrate them for their faults, I think we should honour stories like "I am Curious (Black)" as the pioneers that opened the way for the more sophisticated comics we have today.
