Dude, Descreteuser chill out. The biggest issue right now is you tone and how it's coming off. I'm not gonna argue that 5'7 isn't short; in the same manner that 6'0 is short next to 6'5. It's all relative man. Most of us here at the forum want to escape the fate of being "short" but that's somewhat, also relative to our starting height. So when a person bellow event he 5'7 mark get's told that even that is short, even if he were to reach it, it strikes subtle nerve. I wouldn't call it a disillusionment, because if we did then the same could have been applied at your own case lets face it.
The last point I want to make is that, as I said, since this forum is built upon the pretext that we want to escape shortness, one must realize the relative and sensitive nature of this. There is a very toxic tone to that word "short" in this forum. Focusing on what society considering short is incredibly toxic, it can make you think dark hopeless things. So please we can be realistic about it, but don't be jerks in context as to how you use that word.
