Please don't post flamebait on HN. This is clearly against the guidelines. While I understand it is a reflection of your own experience, it's caused one of the worst flamewars I've seen on HN in quite some time, and we all have to take some responsibility for how others will respond to the words we use.
There is a lot of racism in your modeling of humanity. You should introspect and determine if it’s beneficial to your life to dehumanize and classify people based on the color of their skin.
Yes they can. For example, an ethnic minority could assume that a stupid white person is stupid because they're white. That would be a pretty clear cut case of racism
I understand the parent's comments have been highly inflammatory, and I've replied to them to point this out, but we need you to resist the urge to respond to comments like this, no matter how bad they are. Other people's offensive comments do not give us license to break the guidelines so egregiously. You've done it before and we need you to stop.
