having a discussion on your podcast doesn't mean your in support of your guests view points.
Gotta agree with @realunlucky here. Now I honestly don't know that much about the company's values or the podcast, but I see that they have 124 episodes. I hardly think that one episode where they bring in someone with a different viewpoint to explain their side means they are suddenly anti gun.
I mean, what are we so afraid of/offended by here? I doubt that the people listening to the podcast are suddenly going to become anti gun due to hearing an opposing view - and if they do, they were obviously way underinformed on the topic. I would hope that most of us outdoorsmen and women are capable of making good decisions based on the available information, and I think it is good to learn about an issue from all sides. Sure it is easier to live life in an echo chamber where we never hear something we disagree with, but that is not going to lead to solid/logical thinking and will likely end up hampering us when defending our side.
