Are you serious? What you need to understand is that people don't like to be told they are wrong, specially a GM who's interpretation of a rule helped him create the interesting scene he has opened up for you.
If it's a player messing up the rules then that is the GM's call to do something about it not yours and by saying "well the rules say this" your undermining the authority of the GM.
The biggest issue I have with rules lawyers is the fact that with all your expansive knowledge of the rules you forget the most important one, and no this isn't something someone just made up, it is in the rule book.
ALL RULES ARE SIMPLY GUIDELINES FOR THE GM TO FOLLOW AND ARE SUBJECT TO THE GM'S INTERPRETATION.
What this means is that what the GM says ARE the rules and if a GM doesn't correct a player on his interpretation on a rule then his interpretation is the rule. If you have any objections about a call, save them for after a game or for during a break in the game, because interrupting the game just to tell someone they are wrong is an a*$$!&@ thing to do no matter how you word it.
The best and only solution for your problem is to simply understand that what the GM says IS the rule and stop interrupting the game
