Those politicians who do take their religion seriously (ex. Sarah Palin) are immediately targetted for destruction.
What it revealed was the lengths Patrick would go to to harm the Church.
You are so right that politicians just “use” their churches to enhance their public image. As for Patrick Kennedy, who said that just because he disagrees with the Vatican on certain issues doesn’t make him less a Catholic. Why do these people insist on remaining in the Catholic Church if they do not agree with its teachings? Why don’t they just find a church that agrees with them?
