Whoa. Wait. There's plenty of women who are interested and have relationships with other women and they're not pedophiles.
Honestly IMO there's no way to gain a better understanding. This is a perversion and in all the cases we have looked at here through the years I don't think we can say "Oh well O.K. I see how that can happen".
Point blank the chick is a louse who chose to hurt a child and not only hurt the child, but freakin put it out there for the world to see.
Grown


* folks who are decent "normal" human beings who are in grown up, adult relationships can be in same sex relations. This in no way makes them even remotely near being a pedophile. Perversion does. Lack of morals does. No da*n concern for children does. Being a creepy freak does.
FWIW are we to know for certain this "person" even knew the woman on her block was an RSO? I only mentioned it since it's in a very small area and seriously close to where she lives. If that other woman is doing what she is supposed to be doing she wouldn't be involved in this at all.
