I think the issue whether porn affect society would be debatable, afterall it creates many unrealistic expectations, such as the noise women should be making in bed, or how fast the plumber guys should appear while topless with 6 packs.
However, they chose the wrong candidate for this. A former sex icon, no longer relevant, now come out and protest against porn, everyone would think her generation is long gone and now she is jealous of the new generation porn stars.
The issue certainly worth debating, but choose a better candidate.
