How do you know this applies here? How do you know if, how, how long such attempts might have been made? How do you know it wasn't his wife who asked to split? We just don't know, so why be so holier than thou at this point? (See my response to Yaelle.)
I will reiterate, a hypocrite is someone who doesn't even attempt to practice what they preach. Dennis Prager most assuredly does NOT fall into that category. People who live according to what they preach and sometimes sin and sometimes fail are NOT hypocrites.
