Why do you say it's going to cave? Gut feeling or evidence?
It's in the Chicago Tribune. They are "editing" the more controversial scenes.
I wrote them an email that I was going to tune it in, but now am not sure.

Also, Rush is saying (and I heard on ABC Radio) that there have been edits made to the movie, due to criticism. Also, ABC Radio says that no one has seen the final version of the movie, prior to airing Sunday night.
Something smells.
Based on the relentless DBM bias, it's a 99.9% sure bet that ABC will cave.
