Javascript libraries and their preferences are always a high tension discussion because at the end of the day, it often comes down to whether you made the right decision for years to come.
I think this quote from this article is a good summary of this discussion: "Scala people don't have time for redditing and blogging, they're busy getting crap done."
While it might seem like all the JS devs are arguing on here over their choices, there are many folks who are silently being incredibly productive with whatever tool they choose.
I was stuck with the Xbox so I had to validate that reality to myself by defending it on the internet.
It's no different on HN.
