OP making a mountain out of a molehill. I listed to the same podcast, there was nothing wrong with the guest. He is part of a hardcore raiding guild and he talked about his experiences in it. Everyone in his groups were playing with the same goals and pretty much all hardcore raiders are the same way. There is nothing wrong with that, it is a niche community that plays by different rules. There is nothing forcing you to interact with that community and they do not effect you in any way.
