Fair house labour, childcare distribution, not threatening to remove children via court order, not presuming men will pay for everything and calling out sexists is decent human behaviour too. Women don't need to read feminist theory to know this.... and yet most women are happy for men to pay for things and for men to be pushed to the bottom of the homelessness queue because they enjoy the privileged position these inequalities give them. Most feminists, male or female, are aware of these issues and will mitigate against them.
You can be inclined to believe the victim. I have no problem with that, what you can't do is then act as though that concludes matters and begin a process of disseminating that information. I can believe someone is telling the truth about believing they've been raped, I'm prepared to wait for the court to deal with the matter before I start calling someone a rapist. Our most prolific rapist here in the UK was a male raping males. He's gone to jail for a very long time.
Is it sexist to call a woman who makes up accusations about her husband an evil bitch? You chose not to do that. You called him an evil bastard and you called her 'the likely victim' - and you did so on the balance of your internalised judgment. The court awarded punitive damages in his favour, demonstrating they believed very clearly he was the victim in this case. What you've done there is victim blaming - and you've done it because he's a man and it confirms your internal schema.
Had the case been reversed and a woman had taken her husband to court for defamation and she'd sent texts to her friends about wishing him dead etc, I'm 100% sure you would've seen this as evidence of her instability and desperation to escape. Your judgment is skewed in favour of women. That's the sexist part. You didn't make your judgment on any of the evidence provided, you made the judgment on a single statement out of context and inferred things based on your bias alone. I did watch the court case, I do have the wider context for statements made by both parties - and I'm not prepared to call either of them evil.
Equality between the sexes.
