Pro-tip: If you’re gonna use real-world history in your writing, especially if it involves genocide or colonialism or any kind of race-based or ethnicity-based oppression, GET THE FUCKING HISTORY RIGHT!
Especially, especially, the social contexts of those societies.
Race, gender, religion, sexual orientation, ethnicity—all of these had (and still have) real and tangible effects upon a person’s status, social mobility, personal and collective power, etc.
In 2014, Barack Obama may be the President of the United States, but in 1814, he’s either someone’s property or living far the fuck away from where he’d be considered such.
To ignore that history, or to make light of it, is a deep insult to those who suffered and died through that history, as well as their descendants.
Edit: AND USE TRIGGER WARNINGS FOR THAT SHIT!
