Sadly, this is true. I'd say most "Catholics" today view their membership in the Church as akin to belonging to a political party. They attend a rally ("Mass") once a week (if that) and pay their dues (fill the collection basket), but I bet most of them would be hard pressed to even say the Grace Before Meals prayer. They know the party's mantra ("Peace, Love, and Other BS"), but they have no idea what the party believes.
