those idiots at /j/ still believe i'm a woman （ ´,_ゝ`）
>willing to believe I'm a girl with absolutely no proof... or maybe they just don't care?
they have two options: doubt you and imply you might have a PENIS, which, in the hypothetical case that the person they are talking to is an actual woman, would mean they offend her and she runs away.
or simply believe you, happily jack off while writing to you, and live for but a moment in sweet ignorance, thinking they have an extremely rare, but not impossible, chance of getting digital pussy.
