Hardly, when talking about brash/abusive behavior in the context of an industry where women are underrepresented, I think it's plenty fine to mention that there might be a connection to be made.

Eh, I don't agree. It's well-observed in social sciences that men are given more leeway to be abusive than women are; one example is how often words like "abrasive" or "bossy" come up in performance reports: http://fortune.com/2014/08/26/performance-review-gender-bias...

For every Walter White or Doctor House or Tony Soprano, how many unlikeable women are there? Roxane Gay writes about this pretty well. http://www.buzzfeed.com/roxanegay/not-here-to-make-friends-u...
> Does the gender issue really have to be shoehorned into every story?
Per above, I don't think it's "shoehorned." And I think it's fine if we talk about it more than we currently do, because there's plenty to suggest we don't talk about it enough or are insufficiently introspective about it.
