I'd have to say, that " I feel indifferent about it." The one thing about SL is that you can do &/or be whatever you wish to be or do. When I first came to SL, I rolled around SL as a 1.5 m tall porcupine. Why you might ask?..Because I could & it was fun & different & at that moment I just went with it, much like my username, it kinda stuck, so I kept it. Although it's not overly surprising that most inhabitants of SL are displaying themselves as humans, or some for there of. Most of the starter avatars are human, so it makes sense, so many roam around as such. Maybe in time they'll find who or what they want to be?. Although this is just MY opinion & how I feel about it.
