I agree with the 'too late' sentiments. The genie is out of the bottle for all of those who were hoping to sneak self id through under the radar. They are currently banging away with that same strategy - trying to galvanise support from unwitting supporters, but that still won't work. They need to re-strategise and try and come up with more convincing arguments, but I don't think this is possible.
When the consultation responses are analysed, whilst volume of responses will be analysed, so will the nature of the arguments raised (both for and against). If some serious and legitimate concerns/problems are raised, regardless of the number of times they are raised, they will have to be considered.
When undertaking something like a serious case review, if the person responsible for someone else's safety was warned by a single person of a danger they need to safeguard against, negligence is deemed to have happened if the person did not attend to that warning and harm was done. If 20 people warned of the danger, whilst that influences how the 'ignorer' is viewed, the same principle applies whether it is 1 or 101 people providing the warning.
The ante will be upped with regard to 'kindness', 'suicide', 'hate' and 'bigoty', all of which suggesting to trans people that hate and hostility exists where it doesn't. Way to go Stonewall et al!
