Odds are that this is a typical lesbo hoax. I just don’t think people who hate gays would carve a ‘come track us down, we’re anti lesbian’ sign in some dyke. It just makes no sense, why wouldn’t they just just put her in a bag of rocks and throw her in a lake if they hated her that much?
I believe the story more if it was three women who had done it to her, it's been my experience that most men who hate gays, actually only hate gay men but are pretty indifferent about Lesbians.
