Meh. The article doesn't bother me. I'm more bothered by how racism against whites is deemed acceptable by the mainstream. I don't like how racism against whites seems to be the last acceptable form of racism in society. The article in the OP is something that only the most extreme are going to defend, so I give no fucks and just laugh at it. Leaving aside the racism in the article for a second though, the conclusion is just stupid. Thinking that things would be all fine and dandy once white people die out, like that's going to fix everything.
You miss the main lesson of history. For most of history, whites (causasians) were a backwater. Africa first, and then India and China were were the action was. Even Russia was in control of Asians until the Vikings took over a northern part. Europe and SW Asians were the backwater after the agricultural revolution spread and even then, it was independently discovered in China and India.
Civilizations rise and fall, not because of ethical superiority, but because of geography and climate. Trade flows from civilizations that have temporary valuable goods.
At times, it has been salt, other times bronze and tin, othertimes, iron or coal. Ethnicity does not determine the value of usable goods. Overall human discovery determines the value of goods.
I could go long into why Europe became a fortunate place to be. Let's just say I did and not make me type for an hour about.
But this too is passing... Europe and its stepson "The Americas" aren't successful because the majority inhabitants happened to eventually be White. It became so because of available mineral wealth when those materials became most valuable.
I could go on, but I hope you get my point. YOUR f**king "whiteness" and mine has very little to do with it. All humans are equally intelligent and able. We happened to live where exploitation was historically likely and gained a benefit from it for a few centuries.
It won't last. Deal with it.
