This isn't how discourse works and you know it. It is eminently acceptable to censure people who put forward racist and eugenicist views even if done so politely.
"Our very survival" is not threatened and you know it. Pretty sure no wealth-controlling multi-billionaires look like indigenous Bolivians.
They can look like Carlos Slim Helu (#8 on the Forbes list of billionaires), Mukesh Ambani (#9), Zhong Shanshan (#15), Gautam Adani (#24), etc. There is no reason why a wealth-controlling multi-billionaire can not look like a native Bolivian.
Of course there isn’t. But you understand that wasn’t my point, yes?
