I'm fairly sure there are many people who play MMOs to get away from reality and how they are perceived in reality. MMOs are fantasy worlds and games like FFXIV made the world well enough for people to feel fully immersed in them. Once immersion kicks in you want to be your character, kick back and forget the realities of life during your time in this world. Why would someone who wants to play FFXIV for the immersion want people to think of them as their real selves instead of their characters?
If people who immerse themselves in MMOs and want to 'be' their characters bothers you so much, find gamers like yourself who don't really care much about game immersion eh? If you want to get to know someone beyond their character then you'll just have to befriend them and earn their trust. Otherwise you are Eolas Solais to me and I am E'lusana Celah.
