"Different personality". You know, I put it like that too, but I don't think it's like, "Okay, I'm on the Internet, so I'm going to manually put on this mask". The mask just automatically comes on. And it's not really a "different" personality. It's still you, and I'd argue it's the youest you of all. If you want to see a man's true colors, give him power or authority, and see how he treats his inferiors, or perceived inferiors.
