Mr Graham, I respect you and you've accomplished more that I will in my life, but I sincerely hope that this essay against "bullshit" and "arguing online" isn't you declaring that you'll be "bubbling" yourself after your last essay was met with wide disagreement. It's possible that sometimes, no matter how smart you are, your experiences have been limited in a way and you're missing a part of something everyone else…
I'm not convinced that most of the aforementioned responses weren't motivated by that. So, given that almost anything pg will write/has written will get the same treatment, why would he play their game by bothering to defend himself?
In fact, there is a pureness to insulating yourself from the cacophony of opinions that you get online: someoen will always have an adversarial opinion and life really is too short to try to address any or even some of them.
If I was him, I would let my friends be my guide to when I'm talking out of ass, rather than randos on the internet.
Is that "bubbling"?
