Find out your sw's registration number and make a complaint to Social Work England with clear evidence why you think he is being biased and misogynistic. Don't say he is twisting your words as that is too vague. Give clear examples. Get someone with a legal background to check your complaint before you send it and cc it to the social services manager. It needs to be clear to the point and non wordy.
All your accusations back up with evidence.
Mention the impact of dv and the fact you think this has been discounted.
Good luck op.
Most sw's if not all come in to the profession to support the vulnerable, those who can't protect themselves.
They are fighting fire with limited resources with manipulative and devious abusers.
It is a sad fact that f there weren't manipulative and devious abusers/ parents/ partners then there would be no need for child protection sw's, would there?
But as we all know there are many killers and abusers of children. So how can children be protected from their own family members? Can you imagine how difficult this is?
It would be far far easier for everyone concerned if both parents did the job of protecting and nurturing their own dc.
Sadly we know that the impact of dv makes it very very difficult for mothers to leave their abusers.
Even hearing or witnessing the abuse of others is considered child abuse due to the terrible impact it has on a child's emotional health. A child doesn't have to be physically attacked, just being in a violent and threatening unsafe environment is enough to cause untold damage.
Women often put up with terrible abuse trying to hold the family together and unwittingly causing damage to their DC as a result.
It's a horrific situation all round and no easy answers as it's difficult for women to leave. Hence the horrendous toll of deaths to women and children every week by men known to them.
There are no easy answers and many sw's would not want to work in children's services and there is a terrible shortage of children's sw's which will have a huge impact on the whole system.
I am sorry you are not getting the justice you think you are deserved but the system itself is broken as there is no way a society can ever do the job of what parents should be doing by default.
You sound a victim of this alongside your DC.
