I'm 38 and am indeed quite into sci-fi. I saw Blade Runner in the theater in 1982. None of that has any bearing on whether that guy is up himself.

I prefer to read things I see here without any context or preconceptions. I'll often get to the bottom of an article or all the way back to the comments here before I discover it was written by somebody I'm familiar with. I thinks that's helpful because it keeps your mind free of bias while you're soaking up what's written on the page.

I'd suggest reading the letter again without any preconceptions and see if it seems a bit self-important.
