Forgot to say - playing roles or having multiple personae doesn't necessarily mean being deceitful or deliberately hurtful to people. It can just be fun. In fact one of the few internet people I have met up with has about 5 different handles on the one site - and she is one of the nicest people I know. Elsewhere I have a handle called The Devil's Advocate - who does nothing but argue with people all the time. No matter what the subject. Nobody takes offence because the name makes it quite clear what the poster is about - and most of them know it's me and sometimes I just enjoy a good argument for its own sake. It is great fun too. The DA had everyone logically convinced that there was no such thing as free will the other week.
