"Torn apart" seems like a really extreme description of what actually happened.
Dude presents a somewhat inflated image of his own special shaman-like uniqueness, Roger started funning on him, and a couple of other people found it humorous. That's tearing someone apart? Maybe you might want to read that thread again. It's funny, and not at all mean. I should hope the kid has the brains to see that it's humor even if his English skills are imperfect.
