You are insane to believe just as many women as men would want to work on oil rigs. There are many other examples: auto mechanics, miners, movers, truckers, construction workers, jobs on fishing vessels. I didn't "cherry pick" one example. Any gritty, dangerous, physically demanding job that assaults your senses is going to attract more men than women.

Just citing a single lawsuit as your evidence that the opposite is true, and extrapolating that to say "the facts don't match your worldview" is an assault on logic and reason.
