Sorry for the wall of links, but I want it to be clear that HN has had massive discussion about George Floyd, BLM, the protests, police brutality, race relations in the US, and related topics. I bet we'd have to go back to Snowden/NSA in Summer 2013 to find something comparable.

https://news.ycombinator.com/item?id=23614128 was on the front page all day today. Edit (12 hours later): https://news.ycombinator.com/item?id=23628394 is on the front page now. Below is a sample of other major threads on these topics. There are many more, but I suppose 52 is enough to make the point.

There are over 15k comments in these 52 threads alone. Let's double that and guess that there have been 30k comments on George Floyd-related themes. (I think that's conservative, since I came up with these 52 threads by ad hoc searching and there have been many others.) There have been 283k total comments on HN since George Floyd was killed (counting [dead] comments, which is generous since most readers don't see them), so if my guess is reasonable then over 10% of the comments on HN have been on these themes. On a site that seeks to avoid repetition, that is beyond massive.

For comparison, I picked the most popular technical topic I could think of, which is Rust. There have been 2664 comments on posts with 'Rust' in the title over the same time period—an order of magnitude less. When you're 10x bigger than Rust on HN, and someone calls that "aggressively removed from discussion", we seem to have left behind shared reality.
