Howard Stern is known for degrading women on his radio show. He is rude, he has no respect for people other than himself, and he has no talent.
Howard Stern is a bully. Think about the way he talks down to people and insults people constantly. Do we need a bully as a judge on a show that so many families watch together?
Why would AGT add a non-talented judge to their panel? Remove Howard Stern and get a real judge.
