Persistent and pernicious heresy most be exposed and fought constantly. We were warned by Pope St. Pius X when he condemned as heresy the Modernist views held by politicians.
The "they" in the sentence was referring to the rank and file, not the leaders. That is, I was talking about several of my relatives (and many others) who know nothing better than to vote Democratic. They are living in the past, and have not updated their understanding of where their life-long party has been going. These are the kind of people who vote time and again for corrupt leaders like John Murtha, because he brings money into their district; it is idolatry.
