Well honestly, I think you should stop getting yourself into it then.
You said you dont want these things to snowball, then why do you roll the ball down the hill in the first place.
So some bloke talked trash about you. So what? Stuff like this happens every day on every server, some people will curse, or argue over some incident or whatever or will moan about being wrecked. If you have to worry about all that you wont have time to race anymore.
Just don't get upset about it, it's part of online gaming. You should not be insulted that easily and look for "hidden messages" or things that make you look bad in every post. Cause frankly, I don't even see that.
And let's not get into the whole demo/S2 thing again, that other thread was bad enough. I for one do not agree with you on that and 90% of the people here don't. More than that even perhaps. The tension is really minimal.
So yeah, get a grip, try to see the positive rather than just the few negative things.
