Can't we all just get along?

Simple as hell........

If you do want to do something about it, you have 2 options;
1) Quit taking abuse from the principal. The FED case book outlines quite thoroughly the procedure to follow. The principal is a "spectator" and you treat him as such. If you have a problem with him, you get game(home) management to tell him to cut his crap out, If he refuses, have game management put him out of the gym. Stop the game until he leaves. If he refuses to leave, suspend the game and write a report to the league/assignor on it. If no one in the gym identifies themselves as home management, then it's up to the head coach of the home team to assume that role. If he doesn't want to, same thing.....suspend the game and write her up. In this case, because you've had previous problems, alert your assignor as to what you'll be doing if you run into problems.
2) Tell your assignor not to assign you to any more games involving that principal's school, and also refuse any assignments given to you involving that school.

If you don't want to do something about it, then quit complaining about it and just go officiate.

No doubt that advice won't help you either.
