I'm curious what psychological pathology drives a non-lesbian woman to want to look like this.
You are assuming that any of them are non-lesbian. For all we know, they are all butch lesbians. If they are straight, I can't imagine anyone but schmoes wanting to be with them.
It'd be interesting to know the history of these women. I wonder how many of them were abused by men and took to building up their bodies to these extremes to feel strong as a way to deal with men.
