I would be alarmed too, except I hang out in diverse US communities. Hacker News is not a sample of the general american population. Increasingly, it is not even a sample of tech workers. Tech workers tend to be rather libertarian, and this has not changed. HN is becoming a sample of Bay Area politics and/or Twitter, neither of which are representative of the USA.

Sorry about the downvotes you received. I’ve been on HN a long time. It is sad to see the great decline of HN. Check out reddit.com/r/TheMotte if you want something a bit more representative and more similar to the HN of old, with its attendant high level of discourse as opposed to the shit-flinging and downvote brigading you see on HN today.
