From a livejournal post on Power Girl:
I don't read Power Girl. Don't know anything about her beyond: blonde, big breasts, related to Superman, !Supergirl, involved in the Crisis.(Edited to show entire post)
That's enough for me. I don't want to read Power Girl. I'm afraid that, if I start reading about her, I'll have to write a fic wherein PG goes through seven kinds of merry hell (in what would, no doubt, suspiciously resemble a fantasy-standard epic quest) to find some kind of alternate-Earth Kryptonite that would work long enough for her to have a breast reduction.
Hey, if I was Power Girl? I'd have a breast reduction. What am I saying? I *had* Power Girl's breasts. (I didn't have the rest of her body though. 'Tis a shame, really.) And now I have sensible C-cup breasts. Kryptonite was not involved.
I've given up trying to explain this line of reasoning to people. Most get stuck on "But you can't take away the boobies!" and then I stop talking to them.
