Kicked for being Lightforged?

Ok, so I didn’t actually get kicked, but I ran a pug Waycrest a little while ago, and while I don’t remember the whole group, I know the tank was a Worgen Death Knight. As soon as I zone in, he says in instance chat something along the lines of “s##t ally race.” As far as I know I was the only one playing an allied race. Later on, another message appears from one of the DPS yelling at the tank to stop trying to kick the healer. Apparently he was initiating kicks almost the whole way through. We finished and he swore one last time at me before leaving. We didn’t have any difficulty in the dungeon, so I know it wasn’t my performance. Just an odd experience I thought I’d share.

Must had been a Kel’Thuzad player. Every time I get in a dungeon with a player from there they try to kick everyone right from the start
