There is no argument that FDR, Eisenhower (WWII), JFK, Clinton had affairs.
70-80% of black children are born out of wedlock, yet we "celebrate" MLK day today.
Reagan married twice.
One of my favorite "true conservatives" is Rep. John Schmitz, who ran for President and was a devout Catholic, quick to criticize society over moral shortcoming.
"Early in 1982, John George Stuckle, an infant born on June 10, 1981, was treated at an Orange County hospital for an injured penis. A piece of hair was wrapped so tightly around the organ—"in a square knot," according to one doctor—that it was almost severed. The surgery went well and the baby suffered no permanent injury. However, the baby's mother, Carla Stuckle, a 43-year-old Swedish-born immigrant and longtime Republican volunteer, was not allowed to take John George home since some of the attending doctors were convinced the hair had been deliberately tied around his penis. Detectives threatened to arrest Carla and take John George away permanently unless she identified the father. Carla then identified Schmitz as John George's father.[15]
During a custody hearing, Schmitz acknowledged fathering John George out of wedlock. He was also the father of Carla's daughter, Eugenie."
