I dunno man, if someone on the internet wants me to believe that they're a girl then I'll believe. I may be one of the minority but I honestly don't see why it matters so much if someone wants to pretend they're someone they're not on the internet
I don't really give a stuff who someone says they are to begin with. Other people here obviously do.
But if it does come out that a user has been telling porky pies then I'm not overly likely to believe what they say next. Might not change anything about how I consider that person, but I won't believe their identity so easily, and I'm sure most people have the same view.
I dont care to have the person run out of town though for having fibbed about who they are.
