I'd make a comment about how you can't always take what those kinds of documentaries tell you at face value, and leave it at that. If I was really that concerned I would try to find out what exactly makes her think it was an inside job. Just because she thinks that doesn't mean she's automatically some off the wall conspiracy theorist. She might be an average person who saw a documentary. But, since you said the date wasn't going well its probably not worth the time anyway.
I agree with you about documentaries, they're almost always biased and always have an agenda or they wouldn't exist. My favourite is the recent BBC North Korea panorama that tried to talk up being fair and balanced and played sinister music over the North Korea footage.
That was a terrible documentary. Half an hour is pointless anyway, but using propaganda tactics to try and criticize propaganda was really poor for the BBC. It wasn't worth compromising North Korean relations for.
I know someone with the Assassin's Creed logo on the inside of one wrist and a companion cub on the other. I don't think I'd ever get one of a game, it's not really a passion of mine it's just sort of a hobby.
