In my opinion, Nathan is hurting somebody - himself.
Through the 1971 Stratocaster thread (and other classics), Nathan has branded himself, at best, a fantasist and, at worse, an outright liar. He then appears on the forum and phishes for compliments. Not the best tactic.
There seems to be an unspoken rule in force that this forum community is not supposed to be unpleasant to Nathan because of his medical issues. Does tiptoeing around assist Nathan to make progress in music and life? Are we just postponing the time at which so-called Reality finally catches Nathan up and bites him hard?
In short, I think the time has come for this forum community to decide whether to continue making special allowances for Nathan - thereby condemning him to a sort of perpetual adolescence - or to treat him as an adult?
