That is not only a remarkably uninformed and foolish observation in terms of the courts but a vile comment about Social Services.
The courts apply logic based on an interpretation of the law and the information before them; they should never be swayed by emotion or to use "common sense"; suggesting anything else makes the law quite meaningless.
Anyone who has a problem with Social Services can always give up their well paid, stress free job, train to be a poorly paid, regularly insulted and frequently threatened Social Worker and improve the service. Until they do so, they would be better advised to hold their tongue (and I am chosoing my words VERY carefully there).
Social Workers are despised by selfish people and a Government that doesn't see them, like Doctors, as being "Wealth Creators" and as a result has no time for or interest in them.
Back on topic, I sympathise with the OP and hope that things work out for his children who are innocently caught up in a maelstrom of illogic and emotion.
Having been through the courts myself, I'd say I'm in a good position to make a fairly valid judgement. The entire experience taught me that an honest approach gets you nothing but mental anguish, hospital visits, and financial hardship. What I did learn is that outright lies are absolutely taken into account as truths, even when cold hard evidence is presented. Logic was most certainly 100% missing
In our case a judgement on another case was made the day before we were due in court. The solicitor told us in no uncertain terms that that judgement would now change the outcome of our case regardless of the strength of the evidence. The reason was very simple - no county court judges would risk their career to rule against the new ruling. We were told it would now take several years before a suitable test case would go through and undo the previous judgment (this has since happened). That was that, the solicitor was right - we were a stroke, a heart attack and around £110,000 down. This is common throughout our courts. Logical? I think not. (This was a probate issue rather than custody).
It's not logical to start from a position that the best place for a child is always with the mother, but that's exactly what we have which is absolutely undeniable. Fathers should not be seen as outsiders. Having to fight to "visit" your children is absurd and completely marginalises a fathers role.
Regarding social services, possibly a bit harsh I agree.
