alt Hacker NewsYou must be pretty new to (not just) online discussions if you consider language policing to be a new phenomenon :)
Personally I consider it equally valid for people to publicly express annoyance with somebody's choice of words and for everybody to completely ignore that annoyance.
It gets hard to ignore the annoyance when the volume degrades the signal. At some point the people who wish to engage with the substance just nope out when they see a sea of banality, and that's all you're left with.
