Not only did he spell poorly and use poor grammar, he completely ignored all professionalism that should be used when talking to people whose deisions and views you disagree with. A better draft of the letter would be much more like:
(I am assuming he is speaking of hot coffee)
Mr Jack Thompson,
I believe that you have made a large error in your newly added comdemnation of Rockstar's game Grand Theft Auto: San Andreas. The "hot coffee" data was not intended for release to the public. The programmers and game designers themselves realised that this scene is far too much for their game and thus disabled and locked out the data. The only reason that the data could not be completely removed is for the simple fact that if they removed the data completely, it would cause major instibility in the software. It was the action of players of San Andreas that unlocked this data on the disc, and you should not hold Rockstar responsible for an act that they are not responsible for. I hope that you will try to do more research on the subject and come to a more reasonable view on this game.
With all due respect,
[Insert your name here.]
There is no reason to lose your head when dealing with people like this. If you talk like he did in his message, it merely perpetuates the person's vision against the people whom he is campaigning.
Erm... DONGS!
