It’s far from inaccurate. We live in a patriarchal society. While your local educators may have selected multicultural textbooks with an emphasis on diversity, it’s not the norm. I received a graduate degree in 2009, and while it was less common at a college level, little of my education was diverse. I now have children in school and am watching the same white, male, colonizer curriculum being recycled in classrooms. Be grateful this wasn’t your experience, but don’t assume it’s the norm in the U.S. It’s not, to our detriment.
