In a way I feel like I might have misunderstood something within my self.

I agree with the assessment but I never connected trolling and trauma, because my personal concept of trolling is essentially a continual escalation of reductio ad absurdum. In that sense it's not really trolling or sarcasm, it's more of a way of livening up overly-serious conversations.

I should probably not refer to that as trolling as the intention isn't to fuck people off, gaslight them, traumatise them...but to soften the mood.
