Kara Trapdoor has a provocative post about SL user prejudice against other Second Life users who roleplay, which somewhat ironically spins off from a Facebook thread which starts with this SLer's rant (lightly edited for grammar):
I am adult I can't roleplay a kid, I am accused or being a pedophile -- I assure you I am not. I am male and I can't roleplay female, I get accused of being gay -- I am not. I am white and I can't roleplay black, I get accused of being racist -- I am not. I can't roleplay an animal, I get accused or being weird. What do you do, roleplay yourself? Where's the fun in that? I thought Second Life was about pretending. Get an imagination.
To which Kara offers her own perspective, including this passage which makes a rather centrist argument for roleplay:
We would like others to [roleplay] how we do but of course everyone plays their own way. If I am not close to someone I don't care, but if I am close, even if they don't look or act remotely close to what they would in RL, to an extent I'd still like to be aware of that if I have formed a real bond. It doesn't mean I would give them a hard time, though. Plus there are rules about age play, just saying, so with that, I get why people would be upset. I think it depends what people are doing with their alternative forms.
Emphasis mine. TL;DL: Roleplay is fine, as long as it's always understood as roleplay.
Another commenter writes:
"SL is one place where you can experience your dreams and fantasies without being judged."
This, however, is entirely incorrect: Your fantasies and dreams will be judged in Second Life by other users -- not by all of them, not by most of them, but you will be judged, and to think otherwise is to set yourself up for shock and disappointment.
Why? Well, it's been a recurring theme in my writing through countless posts, but to summarize it here:
