The last Birds of Prey review and G-Man's latest blog have stirred up on old sentiment of mine that I feel the need to express: Forget practicality when it comes to comic books.  Everything thing you see in a comic book (buildings, characters, clothing, objects) is there to communicate not just the story but a visual aesthetic. Trying to rationalize or reason why things look the way they do, or how they work looking as they do, is completely pointless. I've never seen someone venture down that line of thinking and come out happier.
And when it comes to physical appearances and clothing of characters, people often try to portray things as if there is some kind of sexist issue. From the 'controversy' of J Scott Campbell's art to objections over the length of Supergirl's skirt, there always seems to be someone try to play the gender discrimination card. The majority of male characters in comics look totally unrealistic too. That's also not a problem. It's just a style. People need to stop trying to paint it as some feminist social issue.
What it boils down to is that comic books are art. Being art and fantasy, they can show us the impossible: Whether it be magic spells, laser beam eyes, alien beings, or just impossibly beautiful people, that is one of the biggest things I love about comic books and I hope it never changes.
