Can I ask, how would you feel about conspiracy videos doing the same thing? Those that present a conspiracy and then show a reporter trying to verify the theory that ends with the reporter indicating they believe "part of [the] story is probably true, but never expresses certainty." I just can't help think that if the topic was aliens or 9/11 instead of the Caliphate and the author was fox news or reason magazine, you'd consider it drivel.
Edit: I didn't actually listen to Caliphate though, so I don't know if it appears done in good faith or not.
The story that they were investigating was completely plausible because it painted a very realistic picture of things that were happening in Syria at the time.
I suppose the one part of this that is potentially harmful and false is that the ISIS member was living free in Toronto (while bragging about it on social media).
As someone who has been to Syria multiple times, I can assure you that US news is much closer to Hollywood than reality.
