Polarization has been happening everywhere not just HN and not just in the US. Othering is a related term.

I like this. Polarization is a pretty good characterization. People are just not treating neutral views as neutral anymore.

Food for thought: perhaps people treating everything as fake news is an unfortunate adverse effect of all the messaging about the dangers of not recognizing fake news.
