If you condone beatings, near drownings, and the entire enchilada, you condone rape as well. Again: what the crew of the Pegasus does is more extreme than what the Galactica crew does, but they’re on the same path.

I think this is what happened on screen with Cally, during the scene with the two members of the Pegasus crew who were boasting about the rape. You can see her growing increasingly more uncomfortable (and more horrified) as she starts to see just what's entailed in treating Cylons as if they aren't people -- suddenly she's forced to see herself in Sharon.
