I wholeheartedly agree with everything Vicki said.
I, too, am pro-life, but I do recognize that given Lois' outlook in general, it is very much in character for her to be pro-choice, and I have no trouble with her so being in a piece of fanfic. In fact, that is how I would portray her myself should the need arise in any of my own writing. But having a character be pro-choice is one thing, having her distorting the pro-life view so blatantly when there is no compelling plot-related reason for doing so is another thing entirely.
Except for that passage, I have been enjoying your story and intend to keep reading it, but I would have been a lot happier with it had the anti-pro-life diatribe not been included.
Joy,
Lynn
