Maybe someone can enlighten me.

I don’t think it’s hard to understand.  Forget the posted guidelines.  If you say something someone takes offense at and flags it the mods will likely just delete it.  It the easiest way to maintain order in the classroom. Some people get offended easily especially if confronted with unpleasant truths,  so that’s that.  Others have thicker skin and can take a lot more. It’s Audiogon’s house so they can rightfully do whatever they think is needed to keep the house in order.  

Yeah if you use the T word expect a deletion. It’s the price you pay.  Same true for the A word.  The P word is right out!

It's very easy. Don't make political comments that would inspire others to get sideways. You might feel that way, but your feelings aren't shared by everyone and some may take offense.

"Congrats and I feel ya. The current state of the country has stolen most of my joy."

Yes it is of course a form of censorship but hey Ozzie and Harriet couldn’t even sleep in the same bed together without offending someone.  Luckily we have moved past all that.  😉
