This cr** has got to stop. This PC is making criminals and/or defective people of all of “the good people”.
The best way to stop it is to confront it head-on.
If you notice, many times when it is confronted, the perpetrators/pushers back down. When they are not pushed, they get away with, become emboldened, and go on to the next conquest.
If there were an outpouring of support -- in person, letters, phone calls and calling out the individual(s) responsible, chances are they would back down.
