I always thought the ideal behind promoting anti-discrimination was to live in a society where skin colour didn't matter but the left are obsessed with skin colour and identity politics and giving special treatment to particular groups, in this case they're basically flipping discrimination on its head where white people are being oppressed. If you told black people that they couldn't use memes of white people there'd be a massive outcry from the same left. All they are really are doing I think by giving special treatment to minorities is creating division and resentment.
They don't want equality, they want revenge for being enslaved.
