@Ox @terryenglish a few years ago I played SL using a female character, because 1) why would I choose a generic male hulk-like lumberjack and 2) there's like 10 times as much stuff like clothing (from which are only like a 1/4 retarded lewd stuff, means it's 3/4 decent clothes) and other equipment for female characters. later I switched to a male character to get a reference to what I observed.
as a female character I did receive more insults, but the majority of people where much more friendly. I could just talk to strangers, just start a normal conversation without being insulted or simply ignored. also people started to talk to me when passing by. as a male character nobody would start talking to you which is exactly like in reality. I've met a lot of nice people, after a few weeks I knew places and items other players (male characters) didn't know about after playing for years. you could argue it's just a game, but SL is about people doing what they want without the bounds of reality. it reflects how they'd act in real life if they wouldn't have to care about stuff like consequences or time, like in any game.
I hope no one will take this as "evidence" for whatever argument, this is a simple observation and not a scientific study.
