A person that gets entirely worked up over something somebody says on a podcast has entirely too much time on their hands. I disagree with plenty of what gets said on podcasts that I watch, I don't always have the same sense of humour as others and sometimes that means I don't fully appreciate jokes that are made. This is life, you move on. I don't understand how people have so very much time on their hands.
The type of people who complain when they get offended says a lot more about them than it says about the subject of the complaint.
Reminds me of how South Park used to constantly "offend" people, so the creators just kept getting more and more offensive to spite the haters. And became hugely successful as a result.
Here's a thought: if you are offended, turn it off and find something more vanilla to listen to. These podcasters don't owe anyone anything. It's entertainment.
