I don't believe I 'm about to do this, but here goes...
I am going to defend Leatherface's right to pick his own name.
I am certainly no fan of Leatherface and he knows why... but Neo, what you just did is a complete abuse of power. His name, while many might find it annoying, is not offensive in any way. And no, its not meant to be read as "I Eat Her Face 69" as some believe, which makes no sense at all because if you are 69ing, it ain't her face you should be eating.
My point is that you can't just go around changing people's screen names willy nilly because you don't happen to like it. Well, you can, but its complete fascist BS.
What maakes the internet so appealing to so many is the freedom to be whoever you like, no matter who you are. You just took that from Leatherface.
