No, it wasn't a dumb weak argument. It's a correct one. People who HATE Skyler tend to hate her for reasons directly related to the fact she's a woman, a woman who doesn't let Walt do what he wants to do.
It's not "exaggerated," it gets brought up in multiple interviews, at panels - it's not a "manufactured" thing. It's an actual thing. It didn't pick up in response to people noticing many of the complaints were misogynist in nature. If it picked up, (and I don't think it did), it picked up because more people have watched the show, and with the increase in audience, there's bound to be an increase in shitty people making shitty arguments about it online.
When the creator himself says he believes Skyler "hate" is probably, more often than not, misogynistic in nature, it's not a "manufactured" thing.
