The mainstream media has always hated any sense of morals and any non-deviant lifestyle. I have always felt that the term "Popemobile" was meant to demean and trivialize both the Pope and the Catholic and other Christian religions.
Can you imagine if there was such a term to denote the names of cars used by leaders of other religions? Or what about an Obamamobile or a Prezmobile? I felt alone way back when I seemed the only one taken back by the Popemobile's first use. But then I'm taken back when the killing of thousands of innocent people is called "ethnic cleansing." I call any such tragic event a Holocaust. But then that's me. What about other "Christians"?
