Right out of the starting gate, you know what jumps out at me? The spelling errors. Up until now, I've felt that PG was a decent writer and a good speller. The man is no dummy (a monster, yes). So, what's up with misspelling "speach" and "concider"? The word "speech" occurs many times in his manifesto. How could he suddenly misspell the word?
This might be nothing or it might mean that he's off his anti-psychotics or mood stabilizers or he's having a "break", mixed state or rapid cycling. I have several adult kids with bipolar and mood disorders and you'd be surprised at how you can gauge someone's mindset by the way they write and compose. Obviously, I'm hyper-vigilant but I've seen breaks coming due to spelling errors in emails time and time again. Very odd.
