I'm surprised that he's surprised.
He, more than most, should know that when proglodytes don't get their way, they whine, attack, whine some more, and then threaten. Some of them actually do carry out their threats.
Chris, you need to go to Proglodyte University and take a couple of crash courses in Safe Spaces 101, Whinging 201 (I think you've tested out of Whinging 101), and How to be a Dick to Others And Really Mean It.
Don't forget to pay your tuition, otherwise they won't let you register.
