The puritanical impulse to hold people to super-high standards of wholesome rectitude in their private lives seems silly to me
The "in their private lives" part stops (not just stops - comes to a screeching halt) when we have incidents in which other people's lives are directly (and callously) endangered. By someone in a high-profile position in the medical profession, on top of that. In fact, that's precisely the point at which we star to call it a "legitimate public interest story".
So it's not a story about puritanical moralistic standards -- or about this guy's "party animal" life on the side (per se) - at all.
