The whole point of the original essay is that there is a great deal of known information missing from standard, mainstream curricula. I’m addressing the fact that there is information that exists and is well-documented, but is NOT included in the average curricula (several books by authors of color as well as white authors are referenced and linked in the essay). Further, I am addressing what collective effect it has on our society when we persist in this pattern of NOT including known information.
Your opinion is that for me to suggest a connection between this absence of information and the social outcomes of racism and collective ignorance is propagandist and divisive.
Meanwhile, racism is still a problem at all levels of society (including this conversation) and mainstream textbook publishers can do better to include KNOWN information in order to create a more inclusive curriculum for American students.
