Who is "us"? If it stands for "the GC community" it is not up to you to decide who belongs here and who doesn't.
Apart from that, I have always mistrusted any division between "us" (beging pure, good etc.) and "them". The world isn't black and white, but grey and coloured (and the colours are the interesting bits). Black-and-white judgments only promote hypocrisy and self-delusion. Self-awareness and honesty should always be welcome.
Please keep in mind that GC is supposed to be "a respectful, non-judgmental place where girl lovers can get ideas out in the open". You only know most GC posters from what they post here, so please refrain from making negative judgments based on a one-sided interpretation of this small sample. Argue about issues, not people.
Surf safe;)
