It's a discussion forum. A discussion is what's happening. You can intepret this as a 'row' if you so wish, but anyone can see this is hyperbole. There are no ad hominem attacks happening here. I've simply disagreed.
This isn't one of those straightforward situations where both parties have benaved like arses and are equally to blame. The culpability is heavily weighted on one side here: his side.
When it comes to the nonsense put out by a still deeply misogynistic society - especially when it comes to childcare issues - it's helpful to challenge these things where seen. Elsewhere on the www there's an established narrative about secretive family courts denying fathers the right to relationships with their children, and about spiteful women - a complete generalization - who go all-out to destroy their children's relationships with their fathers in a way mostly detrimental to the interests of the children. Women are evil, nasty shrews. Even when their behaviour is outwardly faultless, they're expected to share at least 50% of the blame.
Why? Because they 'chose badly'. Because, after a decade, they've had the temerity finally to tell the media they don't much care for having their names constantly tied with their ex's slow-motion public car crash.
The spiel that women must constantly take accountability for men's behaviour is way beyond tedious.
