Pantload of leftist gobbly gook.
It is not about genuine “racism”, it’s about a political weapon to be used against anyone that doesn’t toe the fascist left party line. No more complex than that.
It’s meaningless otherwise. The dirty little secret that no one has the nads to say out loud is that you can dislike anyone you want to dislike, for any petty or irrational reason that you want to use, skin color included. As long as you leave them alone, inflict no harm on them, it’s your business. If you don’t like short, fat women with red hair, that’s your business if you leave them alone and basically mind your own business.
And that right there is the entire reason why the "race card" is such a powerful weapon for the left. They want to control every thing about our lives and thinking.
