'Troll' is a term that comes out of Usenet forums from years ago, before the 'Internet'. (Arpanet wasn't called Arpanet yet - and most of the general public didn't have access yet.)
Anyway, a 'troll' was someone who made outrageous comments solely to get people upset. If you're wondering where the phrase "don't feed the trolls" comes from, it was those forums.
This NYK guy doesn't fit that pattern. I 100% disagree with him on his orange leader. He doesn't understand that it's rude to SHOUT. But I'd hesitate to call him (her?) a troll.
