That is not a white power sign. In the US it means OK. In some other countries, particularly countries where brown folk like AOC originate, it can mean the same as when we extend only our middle finger. Nowhere does it mean white power except perhaps in the demented heads of the media. Did AOC just flip us the South American bird?
Looks like the media wants us to forget that the notion of the “OK” hand gesture being a “white power symbol” originated as a 4chan hoax.
