Yes, I think Firefly and to a degree Dollhouse had the same problem - Whedon chose to play around with a highly offensive trope, which alienated roughly half of his core Buffy/Angel audience.

In Firefly - it was the Civil War/Gone with the Wind/Western Trope...and in Dollhouse it was the Whore/Sexual Violence/Rape trope. I've seen others play around with similar tropes and subvert them, but they did it more subtly and with a bit finesse, and even they had issues.
