“These people will be the ones to turn us all in when the time comes.”
They will and they will be proud of themselves for doing so.
I suspect most of the “Karens” you see berating others for insignificant and minor actions are presidents or board members of their HOA. I’ve watched video of a lady practically terrorizing a young child of about four for writing on the side-walk with chalk. You know the large pieces of chalk that come in a package that is labeled “Sidewalk Chalk”.
They probably have already compiled a list of names. These are the very same people that ratted out all of the other little kids to the teacher in kindergarten. They get some sort of thrill from the tiny speck of power that they feel from that. I used to manage an HOA. I have met many people from both sides of the coin. The control freaks were the worst though. Some would have happily instituted capital punishment over color selections. Others seemed to take great joy out of trying to destroy a family over some perceived wrong.
