I mean, I agree that practically PG will never feel any serious repercussions for saying whatever he wants _because_ of his wealth and influence. I don't think that's healthy (as wealth and influence are often afforded to people due to privilege or luck instead of ability, wisdom, or empathy) but it is how the world is currently.
The cancel culture boogeyman generally doesn't destroy lives, which makes one wonder why people like PG feel it so important that they need to write essays decrying it.
