So, what is the point of the blowjob scene? Just to give Zoey an excuse to get on her soapbox? Does it have any bearing on the plot or character development at all? And what did fundamental Christians ever do to the Casts?

If you're going to have your protagonist rag on an entire group of people, don't make what she rags on so vain and shallow, and especially don't make your own protagonist exhibit some of these same features. Jesus.

Zoey sees this as "More evidence of the stupidity of humans"

I think we can add " grade A hypocrite" to Zoey's growing list of negative qualities.
