No I think she indeed is semi-consciously drawing upon stereo-types she holds concerning the beliefs of conservative Christians, noting what thinks is cognitive dissonance between belief and action on the part of the Christian Palin and calling it hypocrisy! I didn’t say it was totally conscious calculation on her part, mostly emotional first response before she had a chance to muzzle her-self and try to shade her real opinions!
You may be right.
Ultimately, you believe she lost her self-control with her rant. I agree with that.
