You're right, it's not OK. But adding your own flavor of inflammation doesn't help. The way we can improve threads here is to 1) flag and downvotes comments that violate the guidelines, 2) comment civilly and substantively. Add information and insight. The way to do that is patiently and thoughtfully. Slow down and resist responding reflexively—it almost always makes things worse instead of better. If you notice something egregious, feel free to email us at hn@ycombinator.com so you can be sure we'll see it.
This is cute, but I now see comments endorsing this brand of hate and hysteria (albeit with a less violent flair) on HN everyday. If you're going to suggest that you haven't noticed this trend over the past year or two then frankly your request for reporting is disingenuous.
In line with the original top comment, why don't you publicly declare that you you'll treat discrimination/slander of whites/men/conservatives/scientists/free-speech-advocates on this platform just as harshly as you would any other group instead of asking me to send you a dozen emails per day.
