Anyone remember Rock's old nemesis [b]The Iron Major[/b], whose iron hand bitch-slapped Rock halfway across the [b]Forest of Forgotten Skulls[/b] before Rock escaped his mountaintop prison? That was a great series!
Also, the first anti-racism comic I ever read was a Sgt. Rock where a racist nazi and a black GI had boxed professionally before the war (maybe in the Munich olympics?), and have a rematch "mano-y-mano" while the war rages around them. The whole time they are slugging it out the Nazi keeps taunting "the color of your blood is black! Say it! The color of your blood is black!" At the end, of course, the GI knocks the crap out of the Nazi and captures him, brings him back to the US lines, and the Nazi has lost so much blood that he needs a blood transfusion. Guess who is the only person there whose blood matches the Nazi's blood type? The color of his blood is [b]RED[/b].
That was pretty powerful stuff when I was 8 years old. Too bad I'm less openminded now than I was then.
