Let's take a closer look at your "ridiculous" maxim.
If ANYONE says ridiculous things then they deserve to be ridiculed.
What if the person is a child in the company of adults? The child says something that is absurd. Therefore the adults ought to poke fun of him?
What if a person is unsophisticated and says something that is out of synch with their sophisticated associates. The group ought to laugh at them?
What if a person is from another country and gets his wording mixed up so the meaning of their expression is odd. Should someone say "don't you mean (...fill in the blank) Ha Ha Ha.
Ridicule is a gleeful condemnation of an individual. Ridicule is not directed at the words a person says or a particular assertion - it is a cruel mean spirited attack on the person.
Those who engage in ridicule are trying to return evil for evil. Ridicule dehumanizes individuals. It is a prelude to murder, assault, and war.
