Yes, I must have self-esteem issues. Let's advance your original implication - that I am dumb because I must not have known that I can turn off voice chat in the game, or that I am not dumb, just - I dunno - obtuse or something - because I might have used the term "without sound" to mean something it doesn't. So your original implication is that I am ignorant/dumb and also incapable of communicating effectively.
Now you've decided to buttress that with the implication that I might have self-esteem issues because I said something about it. Once again turning it on me with the implication of a personal attack. Of course you are smart enough to qualify/obfuscate your posts to allow for some wiggle room in the interpretation, like a proper troll.
I'm just a drive by observer of this thread who doesn't honestly give two shits about how it all turns out. You, on the other hand, appear to have a big enough issue going on that you are three pages deep into a thread about you trying to prove you don't cheat.
Self-esteem issues, indeed.
