Hatred in politics get out of hand?

Do any of you watch Hannity on Fox News? Have you ever seen that part where he does the hate meter? Isn't that rediculous? I'm sure alot of people get this kind of hate mail or whatever on their radio shows. But is just goes to show how low people can get. I mean isn't Hannity entitled to his opinion? Isn't he a free American just like the rest of us? Why do people call him and cus him out, call him names ect. I know they have the freedom of speech too. Its okay to disagree, but I just cannot believe the slander that he recieves. I personally like Hannity. I think he is a Patriot and a good citizen of this wonderful country.
