That is just plain ignorant, Shubi. Sean Hannity could run circles around you, intellectually, anyday of the week.
In addition, having liberals on destroys the left's argument about conservative bias. It shows up the other networks as being the partisan hacks they are, since they never have conservatives on to the degree that Sean has liberals on. As Rush says, when liberals are saying stupid things, get out of the way and let them. That's all Sean does.
