I agree that the coverage in the media makes frightening reading. And sadly, we've seen it all before. Your final paragraph outlines the real, broader social issues whose ugly, horrible colours are having a bright spotlight shone onto them by this case. It's an imbalance of power; inherent misogyny in an overwhelmingly patriarchal society. Look at the hatchet jobs the media has done on: Lindy Chamberlain, Joanne Lees, Meghan Markle, Lily Allen, J K Rowling, Rebecca Adlington, Peaches Geldof, Beatrice and Eugenie Windsor, Heather Mills, Diana Rigg (she dared to ask for a pay rise putting her on an equal footing with her male co-star) Lily James ... add names as desired ad naueam, you'll find many, many more.
Look at the names used to describe those women. Homewrecker, whore gold-digger, doesn't-behave-like-a-victim, liar, slut, mercenary, bandwagon-jumper, attention-seeker, drama queen. How often do you see the same descriptives used for men? Even insulting language is more taboo when it refers to female rather than male anatomy. Compare 'prick' and 'cunt'.
Of course, none of this is relevant to the case unfolding. I'm not immune to the fact that it also informs my own bias, given the potentially catastrophic effects on women should Heard lose, in a society that's already more comfortable with women as out-and-out liars than men as abusers. He's clearly abusive. She just as clearly - been proven to have - lied about critical issues. She might be telling the truth about some of it, but doubt has been cast on her own credibility as a witness. I don't thank either of them for the disservice both have done to victims of sexual and domestic violence.
In the end no one cares what I think. It's what the jury thinks that matters, and without all this outside context they have one question to determine. Did Heard defame Depp when she described herself as a victim of domestic abuse? And of her countersuit: did Depp use the court system to try to stalk and humiliate her, and is he guilty of orchestrating a smear campaign against her? As far as both suits are concerned, I think it's only the latter point that's in question.
