Whether a person finds truth in so called " humor " depends entirely on the person. For example. Many thought George Carlin was funny. I thought he was a raunchy, immoral idiot pushing a liberal and Godless political agenda under the guise of humor.
Yet, many people found him " funny " Why? Because they themselves are raunchy and immoral. Back in ancient times in the Roman Empire people would cheer while gladiators and animals ripped each other apart.
Why? Rome was corrupt, and as a result of that corruption collapsed. People will find themselves entertained with that which is what they're made up of. If they are raunchy, immoral, perverted, calloused, and cruel, they will find those things entertaining.
