Hi SuitedandBooted, let me start by saying I have absolutely no problem with this petition - debate is good! And if people have fears it is absolutely right that someone in an official capacity should address those.
I wanted to put my understanding across on some points you raised earlier though, just in case it clarifies anything:
Those of you who are "Meh" about this issue, I presume you are OK with;
Men on All Women's Short Lists
Let's take the example of the Labour Party; they have decide to allow transwomen on their all women short lists regardless of whether or not they have a Gender Recognition Certificate. So being able to get a GRC through self-ID won't make any difference.
Men accessing positive discrimination schemes aimed at women
If those schemes accept transwomen regardless of whether or not they have a GNC this situation will stay the same, as above. If they only accept women with a GNC, self-ID won't change that.
Men in women's prisons
Transwomen are already held in women's prisons by default, however all prisoners are assessed on the individual risk they pose to other prisoners. Any prisoner held in the women's estate - born male or female - can be held in the male estate if they are deemed to present sufficient risk. This wouldn't change if a prisoner held a GNC and had obtained it easily (or dishonestly) through self-ID. They would still be assessed on their risk.
Boys at girls schools
I'm pretty sure children aren't and won't be eligible to apply for a GNC, so self-ID wouldn't make a difference here.
Men on all-female hospital wards
There is already a policy to eliminate mixed sex accommodation in hospitals, except in exceptional circumstances. I assume they'd go by the sex on your medical records. Assuming that gets changed when you get a GRC (I don't actually know), I suppose people could self-ID fraudulently in order to be able to access women on hospital wards in the event that they find themselves ill enough to be admitted...
Men competing in women's sports
Transwomen already compete in women's sports. There is a clause that means even with a GRC the sports governing bodies can impose restrictions. Easily obtaining a GRC won't change those restrictions, or that one would have to satisfy them.
Its not just about changing rooms and bloody toilets.
Neither of which would be impacted by self-ID as neither require a birth certificate to enter.
Women deserve a say on any change to the law that is going to have far reaching consequences for all women and girls
Absolutely no problem with that - entirely reasonable. I'm glad carryondoctor asked if anyone has an ideas who would or should be consulted though, as I'm interested too.
Sorry for the long post, hope that helps!
