He knows exactly the kind of backlash he will receive and is prompting you for it intentionally. He's not writing for you or to you, and he cares not a whit what you think.
He's writing to and for people like him, trying to help them put words and clear thought to vague understandings and apprehensions they've been wrestling with.
He's not self-aggrandizing but student-aggrandizing, as the headmaster of a school of thought that he values deeply. If you hate the headmaster or his style or the school of thought, that's wonderful, but it's not at all relevant to his aims. I hope this sheds some light on the bigger picture for those unaware.
