When people rally in ignorance, they'll find anything to pick out and magnify. Like CrstWpn. said, I'm not surprised that folks are finding any and everything they can to toss hate at.

The text version of our in-game emotes don't make sense anywhere else on the internet, that much I'll agree to, but I'm using them in a place where everyone viewing them knows exactly what they mean and where they come from. I don't know why a /salute would annoy you.
