It's true that other people have problems, but that doesn't reduce the amount of discrimination against African-Americans and other minorities, or help the problem. An assumption behind the parent's "bet" (no evidence is given) is that discrimination against African-Americans isn't especially problematic. I think that needs to be supported against the mountains of evidence that say otherwise; IMHO, it is like claims of climate change denial - it's easy to make the claims, but the evidence is overwhelmingly otherwise.
A sad fact of HN is that there are no voices of African-Americans, or at least very few and they don't share their experiences (not that I blame them; it's a hostile place). Other people with no experience like to share their opinions, but that is as valuable as me talking about what it's like to work at Microsoft - I've never worked there so my opinion isn't worth a lot. The lack of people experienced in this subject is both an outcome of generations of discrimination - African-American families often lack the wealth, income, and educational history associated with higher education and SV jobs - and a cause of it: We don't understand the problems. We're just BSing in the dark.
I think it is to African-Americans, women, and other minorities. For example, broad stereotypes and criticisms are made, and frequently comments that say, for example, that racism is a problem, is voted down (my GP comment was voted down to -2, for example) and commonly harshly criticized. When those issues come up, most comments criticize any differing perspective before they are expressed. On the surface, there is very little interest in listening to other points of view - though I suspect that is the intent of the inflammatory commenters, to shut down discussion.
I think if you did a survey on HN users you would see that most of them think that racism is in fact a problem - that it is not good.
Also, I think its important to consider your comments holistically when seeing how they are received by the community. Of course you believe you comment communicates one thing, but in addition to that you have tone, other claims, and defenses. Any of which can result in a downvote.
