Pasha Eshghi seems to just be an anti-NYR social media troll. If you look at his social media, like 90% of it is anti-Rangers hating. Trouba's biggest mistake is to even engage and give this guy attention.
It also seems fairly obvious that Spittin' Chiclets just have him on the show, so they can have that guy spout controversial 'hot takes' that they know will trigger a reaction, but if the backlash gets too hot they can just disassociate and cancel that guy rather than getting auto-cancelled themselves i.e. a classic talk radio schtick. It's cheap, no value content aimed at their room temperature IQ following.
But Trouba *should* know all of that and know how to deal with that stuff. It's common enough in sports. Even college athletes have to deal with that crap, and they're 18-19 year old kids, not 30 year old veteran leaders of an NHL team.
