Would you care about Margie's past? [SPOILERS]

Put yourself in Francis' shoes. Would you care that Margie was a willing participant in incest?

Personally, I wouldn't. As long as it was in her past, and didn't so much as affect her as person in the now, I wouldn't care. I would think it's slightly weird, but I wouldn't have reacted in the same way Francis did (IE; running off like a dog with his tails between his legs, avoiding her, and acting awkward when they were together).

I lack a lot of the morals that other people have, am an atheist, and look at things from a Freudian angle. So maybe that explains why I don't care that Margie willingly participated in incest. As long as she wasn't going to be going back to her brother while she was with me, or isn't hiding a freak child in the basement, I wouldn't mind.

So, what about the rest of you? Margie, who is a total babe, tells you that she's had sex with her brother. Does this change your feelings for her? Do you continue your relationship with her? Interested in hearing your answers.
