When a person is not able or willing to rebut another person's position they resort to argumentum ad hominem that is...attacking the person instead of the position.

That is what Rush Limbaugh did in this case...he attacked the person instead of the position.

Some may remember when he subsitituted on Pat Sajak's talk show? He attacked and belittled people with AIDS. The audience became so offend and Rush so frightened...the audience was removed.

This is a standard tactic of a certain kind of person. It is sad and it is sad to see it here on PetTalk as well.
