The interesting thing about Rees-Mogg is that he isn't actually stating his own personal beliefs, he's stating the beliefs of the Roman Catholic Church which he is doctrinally obligated to follow.
Secondly, and this is what I have the real problem with, is the flippant nature of his response to the question about abortion following rape. If he had come out with something along the lines of the act of rape is horrific and the mother needs all the support and help she needs / the ability to offer the child for adoption etc but, as part of my religious beliefs, I belief that no matter the barbaric nature of the conception, a life has been created, I could have quite easily accepted it a an articulate argument for the point. But to simply come out with, "I'm afraid so." is borderline sickening! It shows a flagrant disregard for the anguish and torment a rape victim has gone through, almost like a Primary School teacher claiming, "Rules are rules!"
Once again it's not the belief that causes the offence but the pathetic attempts to explain it.
