Polite avoidance of people is almost the the same or mirror spectrum of ignoring people and being overly direct about it.

Similar to how passive aggressive over time and being aggressive directly is very similar result.

Here is an alternate arrangement of text to show Polite + Ignoring are similar mirror spectrum:

➡️ polite avoidance
(being indirect about it)
--------------------------
➡️ ignoring people
(being direct about it)

➡️ Polite avoidance can be aggressive from people who have power and don't give it up or share it - so they just ignore people over time instead and hope the "go away".

That could be considered passive-aggressive as responsibility is shirked to answer an obvious or repeated question and leave it hanging talking about things around... At the same time someone overly asking questions can be similar in aggression but usually there is a clear power differential to why the subject is being asked or even exists (management not showing their plans for example or what they chose in the past) and it's a power play of sorts to let people stay frustrated and get to boiling point wanting them to do something rash and effectively kick themselves out (of the forum or job) instead of addressing the / or subjects.

Especially if you are providing a service or relationship but don't want someone there / don't see the point of their existence and ignoring how slack you are in reply - this might be used. Admin might even enjoy others suffering or the "I need you" factor and frequent messages for help (attachment theory)

Polite ignorance can make people look good as it seems wild someone is lashing out, while ni the background the people in control are still doing similar to other masters just less obviously.
So if you see people get angry suddenly it can be over time it's got to them, and really it works.

Which is why it's better for humanity to sort things sooner than let them hang and for it to build up in people to them to potentially take that accumulation and vent it elsewhere.

➡️ ignoring people (being direct about it) is more obvious and clear. Telling people what you think and being direct about it. Not much more to say about this section as the post was about how similar this point is with the polite kind.
