Who is the Worse?

I have a great difficulty understanding how people can accept lies and distortions about people that they here on television as the truth. The recent situation with Bill O. and the ongoing one with Rush L. is a great illustration of this ridiculousness. Why they do not bother  to either listen to  them on the radio, watch them on t.v. or check their web sites for validity is unfathomable to me. I really do not know if the people that tell the lies or the ones that believe them are the worse people.
