If I'm not mistaken, he's not upset about the posts. He's more upset that a few people Reported him which is, in fairness, understandable. And it's not his fault if people interpret what they want about the MC. He nay have had a hand in creating the character's storyline, so who better to explain what type a person the MC Is, rather than what he expects people to see? His statement about expecting facepalms seemed valid too and those people Surely would have if he hadn't said so but they Escalated it by reporting him, as a way of saying, "Oh, you think that you're so smart but we'll show you."
I can understand his indignation. Let's say that you did a painting of a mother and child in a field. You paint the scene as such that the mother is being chased, in play, by the child. Now you show it to someone else but they ask you, "Why is the mother Abandoning her child?" You go on to explain the scene but that person gets angrier and calls your painting trash. You're frustrated now, so you tell them, "Well, that's not what it is. If you don't like it then it's your problem." You put it somewhere and cover it, then the person leaves. A couple of days later, you have a dozen people outside your home saying that you promote child abandonment. That'd piss you off too, being bad-mouthed because of someone else's misinterpretation. Now, what was supposed to have been something that you wanted the world to see, winds up never being seen out of said frustration. The sad thing is, these types of things happen in real life, every day. Every one is going to be a little sensitive when they feel like they're being attacked and, given that they narc'ed him out, I wouldn't want to talk to anyone either. Having to explain yourself over and over is exhausting.
