To have an opinion of that person would entail my acknowledging said person. That being said, I try my best not to think of Coulter. Disregarding Coulter's existence makes my day happier
The same opinion that I have of Fox News, Limbaugh and Beck.
I do not watch or listen to any of them, so I have no opinion of them.
I do however find it amusing that liberals spend as much time as they do listening and watching them. Hell, come here on any given day and you will find liberals telling us what was on their shows.
