Isn't Ruth... she's a fictional caricature creation. Furthermore, the strict division into butch and femme is not all there is to being a lesbian. I still have nightmares from when I first came out and arrived in the UK (very early 80s). Israel didn't have a scene as such, so the whole concept was completely unknown there. I was so confused by my inability to fit into one of only two available options because I was basically very much myself (...) that I almost decided that I must be straight.
Nowadays, thankfully, (gender) identity is a lot more flexible and varied and allows for individuality (I know the lesbian thought police probably has something to say on that too...). There are a million types of butch definitions, some inner, some on the surface, and several continuums entering into many different dimensions. It's a science all on its own.
