Truly, the glory of comic books is this: There is always plenty of good-natured sexism to look back on! As in this excerpt:
What I love most, I think, isn’t even the casually mocking and misogynist dismisal of Power Girl’s grrl power (see what I did?) by Green Arrow and the Star-Spangled Kid. No, I think what I like most is that they are more skeeved out by her take-charge sexuality than by the fact that the man Power Girl is hitting on is Superman…the Earth-1 version of her own cousin!
