Tweeting that Scientology is 'evil' (but Mormonism OK), Murdoch took time to cement his opinions on important social mattersRupert Murdoch took time out from his reverse ferret* over UK newspaper ownership on Sunday to air his views on Scientology, Mormonism and the weighty issue of Tom Cruise's split with Katie Holmes.In a smattering of tweets, the octogenarian media mogul appeared in combative mood, dismissing the New York Times as "boring", Scientology as "evil" and the British government as "weak".It comes on the back of a week in which he snubbed the English while announcing the hiving off his UK publishing arm into a separate company, and criticised Republican presidential hope Mitt Romney for failing to look like a challenger.On Sunday, he added more names to the list of people we can assume won't be getting a Christmas card from Uncle Rupe this year.First off was Cruise, whose split from wife of five years Katie Holmes was announced on Friday.Holmes has reportedly cited her ex's ties to the Scientology movement as a reason for their separation.
