Keep in mind a couple of things as you go searching back through his writings:
1) This guy was a "Little Ward Churchill". A lot of what he posted is plagiarized, containing no attributions to other authors, though a quick google shows the text to be lifted verbatim from some other author.
2) I don't have the posts at hand, but a couple of other Freepers have pointed out that he seems to be doing a lot of "projecting" in that he takes experiences that other ex-Pent forum denizens have posted about, and seems to think that they actually happened to him instead.
I don’t recall the kind of ‘reverse projection’ that you seem to be convinced of.
He RESONATED or felt he RESONATED with a lot of other kids what REPORTED similar horrid backgrounds as he perceived, reported his to be.
That he plagerized or copied other descriptions of trauma, anger etc. does not diminish the import of those descriptions at all.
HE OWNED THEM AS HIS OWN—emotionally, experientially, essentially, functionally, more or less literally.
