you do need to be more careful with the forum rules... and it's probably not a good idea to complain too much about Negative Reps if you, like you say, don't care about them... I used to Neg Rep anyone who seemd to make such a complaint...
just learn to let things slide. Rather, maybe these comments aren't helpful, but you could still look at some of those posts and manage to figure out how to improve your arguing and writing. Some neg reps are done out of sheer spite and assholeness, but others have a legit rationale behind them, even if it's not evident from the rep comment.
