They're the two races with the highest IQs overall. The elites don't want that so they purposefully use Whites as their whipping boy and scapegoats for everyone else's problems while trying to pander to Asians so that they could bring in policies that dumb them down completely.
Then again I'm preaching to the choir. I fear that we won't have long before intelligence is frowned up and being stupid is a virtue.
The anti-Asian propaganda is to create an atmosphere where you won't criticize China anymore, because it'll be illegal or socially harmful to do so. All intentional on China's part.
