to write the unwriteable wrong

I'm absolutely with you on that; it's one reason why, given a choice between a variety of options for subplots, I like to offer some representation of people who don't get that very often. (Although sometimes the plot has other ideas. I was all happy about having a happily married-with-children lesbian couple in the graphic novel I'm writing right now -- lesbians of color, too! -- except that the plot is evolving in a direction which is putting them in imminent danger of being written out, unless I can find a new subplot for them.)
