I didn't catch the reference. I apologize. My bad.
It's a Gandhi quote that resonates with racial perceptions. No one need change their race(I hope that goes without saying) but if you don't want to be perceived as some kind of problematic, irrational, menace to society, be the change you want to see. I feel it's pretty easy to grasp. Reacting negatively like that does not help move forward the change we all want to see.
Wasn't Gandhi racist as fuck?
