Let us show some maturity even if this is just the internet. To maintain order in our community, we must not hold grudges against people who seemed to put us down. Whether in PvP or just random dilly-dallying, we must never forget our manners. A true respectable person shrugs off defeat like it didn't even happen, and learn from their mistakes. So what if they won over you? It takes practice and lots of perseverance to be even half-decent in an actual match. We are in no position to blame them just because they won. Its their glory, and its your thought to ponder on. Next time, who knows and you just might win. THEN it will be their turn to learn from their mistakes.
Its a give and take world, and everything is just fair as it is. Unless of course, you used some 1337 hax to dominate your opponent. Show some sportsmanship and respect and it will come back to you. Show rudeness and you'll end up a social outcast. Lets face it. We can't live by ourselves even in the internet reality we're in. Sooner or later, we'll make enemies and friends, as well as formidable rivals and dependable allies. It is up to you to balance your temper.
Now play nice and stop using insults for fun. No more a and n words and other yadda-yadda. This goes for everyone ;D
