I didn't find any amount of "so hostile" comments.
I think what makes the vibe hostile it that this is the sound of social cohesion tearing apart and there is the implied worry that "it might get hostile" unless things are fixed.
But that is not the same thing as hostile. It is discussing a problem.

Attack on one's validity as a member of society:
> Whenever I encounter this attitude I like to remind that person that they should have no voice, whatsoever, in what happens in government and politics anymore (https://news.ycombinator.com/item?id=39342079)
> Kids aren't expensive. They're a distraction from dopamine and career advancement. [...] they'd rather jet set than settle down. [...] Instagram and the endless feed of social media, internet, and things to do. [...] Nobody I know wants to give that up. (https://news.ycombinator.com/item?id=39341734) (this one is not hostile, but it's still in put-down territory)
Whether one views these as hostile can perhaps be a matter of perspective, but these posts do not invite cordial, level-headed debate.
Given the amount of comments I would still not say the topic is particularly hostile? Or am I desensitised maybe?
I mean, if the question is React frameworks, there is way less risk for philosophical fistfights and outbreaks, rather than a discussion about how people live their lifes.
