Funny, when someone was falsifying documents about me and forging my signature, attempts to raise awareness to my issue were also downplayed as "airing dirty laundry". Is it a new buzzword or something to help large businesses punch downward?

Keeping things private is often good manners.

Sometimes good manners are not the only principle at stake.

If you go around shitting in other peoples beds often enough then eventually someone is going to hold up the sheet and say "hey look at what they did".

Want to shit the bed and get away with it? Do it in the privacy of your own home and involve as few other people as possible.
