Thinking back to some of his earlier work, I suspect our thinking has changed more than KB's.
In the years since I watched his shows like the Civil War, there's a much better awareness of the subtle and not so subtle mentions of the politically correct in all of the media.
I'm watching it for the historical aspects, what I can learn, and just filtering out those other items as they occur.

Thanks for that Matt Walsh video, magna. An interesting watch and confirmed my suspicions about the agenda. It was also enlightening regarding the the insidious way Burn's propagated the Leftist/revisionist propaganda throughout the series.
