settlersplaining

Attempting to explain something you yourself actually lack the knowledge needed to understand to someone who actually does have that knowledge, an act often performed by settlers to Natives
For examples see twitter

Person 1 "Why is he comparing the difference between a school of fish and a herd of buffalo to two human ethnic groups and where does he think buffalo would get prejudices against schools of fish in the first place? How does any of that 'prove' his belief that there is only one Native American culture in all of North America?"
Person 2 :He's settlersplaining, don't expect him to make any sense"
