I agree with the OP.
Good-natured banter is fun.
Calling it "negative interaction" is just reductive.
The community here certainly perceives normal, good-natured banter as something really bad and very offensive when it's nowhere close to that. Which is kind of sad, because as I said, good-natured banter with strangers online is fun.

If a fresh new sprout pulls up to a group of veterans wearing their sick armour and ultimate weapons and goes "sup noobs", why would your first thought be "A new player who's very arrogant and thinks very highly of themselves came here to talk down to us and annoy us"? I just don't get this mentality xD Wouldn't it be more fun for you if you thought about it slightly differently, have a little laugh, have a little fun while "actively AFK'ing" (not running any content but still at the PC).
MMOs are extremely well-suited for these sorts of social elements, and recently I've been watching Shobek's streams of this game and he's taking full advantage of this social element and he's having a blast, along with everyone else around.

Not all banter is negative interaction! I trust it is within your power to tell the difference with decently reliable certainty between actual malice or harassment and good-natured banter. You can make this particular social element of the game more fun for yourself quite easily, with only a slight bit of mentality shift! And if you don't care about this particular social element, that's fine too, you can ignore it, but please don't demean people engaging in good-natured banter with strangers online in an expansive virtual world that MMOs provide, as some sort of terrible people. That's just not right.
