There's obviously a difference between liking the cool character of Walt more, and the outpouring of hate the Skyler character (and even actress) received.
And I think it's perfectly reasonable to conclude a lot of this was down to people with dodgy attitudes to women (or, you know, idiots). Not all of it, obviously, but the strength, proportion and similarity of it clearly indicated a problem. Enthrenched in the wake of things like gamgergate.
If you didn't like her that much, coolio (I wouldn't rank her in the top 10 characters myself) but if you found yourself palpably antagonised by her, I reckon you've at least a burgeoning talent for idiocy.
