The big online communities I'm a part of are twitter, reddit, hacker news, and facebook.
It's true that hacker news seems to be different from those when discussing culture war topics. With hacker news being father to the right than twitter and reddit, and more center right than my facebook feed.
One conclusion is hacker news exists in a right wing bubble. The other is that twitter and reddit exist in a left wing bubble. Given that the median voter in the last election voted for Biden, but just barely, and maybe voted for a republican senator. And even the people arguing her being let go was justified are probably pretty center or center left. I would guess your "elsewhere" exists in a ideological bubble that is much stronger than the one hacker news exists in.
