Don''t be silly - nobody ever suggested not modelling healthy relationships.
Pretending bad husband don't exist won't make them go away. Pretending that anybody said women are responsible for men's behaviour won't make bad husbands go away either.
It would be far better if you did not keep inventing things to reply to and just stuck to what has been said. Here are some of your strawmen, and why they are incorrect:
"Rather than imparting our trauma to our daughters"
I'm sorry you're doing that - if you're not, not sure why you are bringing it up since giving girls reality based practical advice to help them is certainly not "imparting trauma" on any level. But living with a bad husband and partner you could have avoided if you understood the red flags can sometimes, indeed, be traumatic.
I think it's far more important that we teach our sons how to be better partners,
Nobody suggested or implied not parenting sons to be good partners. It is incredibly important to teach our children not to put their hand on a hot surface, and it is incredibly important to teach girls to avoid red flags in men where possible.
"Women and girls should not have to be responsible for the poor behaviour of men."
They're not, and nobody suggested or implied that.
"But I don't think imparting this level of cynicism is particularly helpful or healthy.
Except it's not cynicism. It is factual, real and practical, it is a guide to behaviour that can indicate a bad potential partner when considering the massively important life changing taks of raising children.
Not all men are awful creatures who can't be trusted.
Literally nobody said this or implied it.
I don't want my daughter to grow up expecting the worst her entire life, what a miserable existence that would be.
Yes, you should try not to instill that in your daughter - but certainly none of the advice here would or could do that, so feel free to impart it to her as a caring mother.
You can certainly choose not to make the effort to discuss these very clear, factual and obvious red flags with your daughter, but you can't simply invent conversations and motivations and reply to them instead of sticking to the discussion we are actually having.
Well, I mean you can - and did - but it's rather pointless.
