Oh I've seen some of his videos and he does make sense. The man isn't an idiot. But it also doesn't take a genius to repeat something that is factually correct that was stated by others before him.
In fact my high school history teacher is the first person I ever heard say, "History should make you uncomfortable." He also said to look at history with a particularly critical eye when there's only one source of the account.
In reference to the latter, take a look at the Battle of Kadesh or Hannibal's "rampage" against Rome. Both accounts are single sourced and both sources had self-serving ideas when they wrote of the accounts.
