Why do certain radio pundits misinform the public on climate change? Take this example from Lars Larson...?

You yourself listen to rhetoric. Why do you have a problem if this man does? Just because you don't believe his opinion, Does that mean your opinions are correct? By the way, AL GORE IS BACKTRACKING ON SOME OF HIS PREVIOUS BELIEFS! He now says, "Maybe global warming isn't as severe as I would like to believe". Scientists aren't Gods. They aren't infallible and can often be disproved. Quit being so BIASED and CLOSE-MINDED!!! Quit believing everything you read, see, and hear! I will personally give $1,000,000 to anyone who can prove or disprove global warming!!!!! By the way, Are you a LIBERAL? Liberals always seem to think everyone has to take what they say as the truth, or as fact. I feel sorry for you that you get so worked up by what these people are saying. Why do you care? Are they harming anyone? If you had any common sense you would stop picking who you think is right and vilifying who you don't agree with. EVERY CHEMICAL WE CREATE DIDN'T JUST APPEAR, IT CAME FROM THE EARTH. WE DIDN'T HAVE SOME POLLUTANT SHIPPED FROM MARS BY A REPUBLICAN, JUST TO BE ABLE TO KILL PEOPLE! HOW THE HELL DO YOU KNOW LIES ARE COMING OUT FROM THESE PEOPLES MOUTHS! I PERSONALLY BELIEVE THAT YOU, AND OTHERS LIKE YOU, ARE THE REALLY DANGEROUS ONES!!!!!!!!!!!! YOU ARE WILLING TO TRY JUST ABOUT ANYTHING TO GET PEOPLE TO BELIEVE, THINK, AND ACT LIKE YOU!!! IF YOU WEREN'T, SHUT THE HELL UP AND STOP LISTENING TO THOSE YOU HATE!!!!! LET OTHERS LISTEN TO WHOMEVER THEY CHOOSE!!!!!! QUIT TRYING TO CONVINCE PEOPLE WITH FACTS AND FIGURES THAT AREN'T EVEN YOURS!!!!
