You did try to list your credentials in the Reddit thread IIRC. And I'm not judging your success and experience against Paul Graham's -- I'm judging it against Paul Graham, Joe Kraus, Evan Williams, Mitch Kapor, Mark Fletcher, Joshua Schacter, Paul Buchheit, etc. All of these people have practically endorsed YC as a Good Thing(TM) and have supported it by meeting with the founders and giving them advice.
You're asking why it feels "combative" and yet your posts basically say that anyone who thinks YC is a good deal is an inexperience make-money-fast cult zombie kid. Surprised?
You'd get a lot more positive response if you went a bit easier on the insulting language and condescension. I don't think that's what you're after though. I think you're enjoying being the outspoken contrarian too much. Enjoy.
