Maybe he doesn’t consider some 4 letter words as cursing. Maybe he considers using the words GD and JC as cursing. There you go - judging someone without knowing the truth.
Maybe Trump also doesn’t consider cheating on his first wife wrong, as long as he marries his mistress, and then cheating on his new wife, and then marrying that mistress, or making fun of a man with a disability wrong either.
So if he thinks those things are OK, are the rest of us supposed to as well?
