It is not so black and white. A person may have been brought up racist, no fault of their own and tantamount to child abuse I would say. Your mindset would exclude any chance of re-education for them. At a wider scale it's also very simple to talk big like you are right now online. But as a hackernews regular I rather imagine you are most likely a middling tech worker, perhaps living pay cheque to pay cheque feeding a family (2.5 kids and a dog). You are, much like the average American politician, very likely to denouce racism and support grand action in private - but much less likely to jeopardise your family and livelihood to back the words up. Hopefully you can see the hypocrisy in asking anyone else to do so from behind the glow of your monitor.
