one thing to say you're a history lover, or like to study history.
whole nother can of worms to go around harassing people over historical inaccuracies in their work or attack them for not knowing who Henry VIII was. Because of course one human being, your hardcore historian self, just knows everything about history and learning it all was totes easy and everyone should do it before they ~*dare*~ to talk about history.

which is what being a hardcore historian in the APH fandom is about ^-^
