The fact that you are telling me (someone you don't know) "...you know far less than I do" and "You don't know what's historically accurate" and all the other "you don't know"s, tells everyone everything they need to know about who they're speaking to.

Thank you for confirming my suspicions!

Check out if my statements were accurate. I realise it's not ego confirming to be told you're wrong but you could really see it as an opportunity to learn.
