I'm guessing some of these more sensitive sorts were never in the military or similar fraternal organizations where you routinely gave affectionately pejorative, often obscenely colourful nicknames to your comrades. Particularly when they did things things arguably jeer-worthy, like, oh, I dunno, rhapsodizing about one's employer. Or needing an illustrated how-to guide to landing an aircraft as an airline pilot.
I guess those day are long gone, but it does strike me as odd as I'm pretty sure I'm closer in age to Generation Snowflake than Harry is.
