What's interesting is that I've had the opposite experience! A lot of Behind The Bastards episodes are well cited and well researched. Robert often reads multiple books on a topic before presenting something, and often quotes researchers/historians whole paragraphs at a time. It's something that I've learned a lot from.

The joking banter and tone helps it go down for me. I wouldn't be able to listen to these things otherwise. It's depressing to know the some totality of what we've done to each other.
