Back in the early '70s, when she was edited, written and drawn by Mike Sekowsky, I think mod Diana Prince was quite liberated without trying hard to be so. I doubt that Sekowsky himself had any sympathy for the women's movement--at that time he was in a custody battle with his ex-wife who had taken their daughter to the other side of the country. But that didn't bleed over into his work, as his Diana was as bad ass as The Bride in KILL BILL or Sarah Connor in THE TERMINATOR.
However, Gloria Steinem who was in the same building as National Periodicals had a conversation with Carmine Infantino to liberate Wonder Woman, by returning her to the old fashioned look. When Sekowsky quit Wonder Woman, there followed many fitful attempts at reforming the character. Dorothy Woolfolk took over as editor for two issues--and that was supposed to launch a new liberated WW--but all she managed to get done were two issues of reprints before she was sacked. Then Denny O'Neil took over and while the comics he edited were nearly as good as Sekowsky's, his short run as editor ended in one of the most unintentionally offensive comic issues.
This was WONDER WOMAN 203 (November-December 1972). Across the top of the cover was written: Special Women's Lib Issue. The nice Dick Giordano cover had Diana's friend Cathy Perkins kneeling, tied up and gagged in the forefront, as Diana comes to her rescue, unaware of a pack of hounds about to pounce on her. The actual story by Samuel L. Delaney was about female workers being exploited by an unfair boss (who looked suspiciously like Carmine Infantino). This was all satisfactory, if a bit heavy-handed and not really fully understanding the issues of the day. But what was really strange about the story is that Cathy Perkins was the liberated woman who was schooling Diana Prince on women's rights--and Diana was the one who was out of touch with the movement. And this was the comic that was supposed to be especially devoted to "Women's Lib."
It just goes to show, that even when men were actually trying to placate feminism, they were so lost in how to do that they couldn't even get it right for one story where that was the agenda. And the next issue was WONDER WOMAN 204, where Robert Kanigher took Diana Prince back to being the unliberated, mousey "men seldom make passes at girls who wear glasses" sterotype that he had turned her into once before.
