On a similiar note, I find that when using the name Jaguar, many people assume, before they get to know me, that I am male. On a number of occassions, some guy would be very arrogant with me and try to fight me. When he finally finds out that I'm female, his whole tone would change and then he'd try to flirt with me. It's really rather funny to observe. Kind of intersting too to see the difference of treatment based on others' assumptions.
Wouldn't be surprised if some of those females were scared and posted as males thinking they were safer that way. You know, all those evils of the internet legends that go around.
