Emboldened by recent political events openly racist people are everywhere on social media.
Revisionist history white washing the past.
So I indulge them, "wow that's amazing, tell me more about how all advances in Civilisation belong to white people".
And they start "Well back 200,000 years ago..."
"Oohh I'm going to have to stop you right there mate. Did you say 200,000? I would like you to explain how all Civilisation comes from white people, without the use of Arabic numerals please."
