I think there's a right and wrong way to do it though. (And as pointed out, bashing was not the correct word to use here and I should not have used it)... I think it's fair to critique writing, and sexist overused tropes. Things don't go away by ignoring it, and I doubt anyone is contacting any writers directly and saying "YOU SUCK" or anything. But venting about how the trope over tired, overused, and sexist isn't bashing the writer. Personal attacks, calling the writer a terrible person, etc... yeah, not cool. Do not recommend. But redirecting the frustration to explore WHY you dislike the tropes, talking about how the writing itself is sexist and wrong (without personal attacks), I think are all good and productive.
