Girls,
The proposed laws done by Mrs Grant were already rejected different times and you should not be surprised at this.
You can just imagine how many politicians, business men and other VIPs (e.g. Rooney) coming from all over the Great Britain have booked at least 1 hour with an escort.... in other words, the stakes are too high to risk... they do not shoot themselves in the feet going along with Mrs Grant's wishes.
So, do not be worried and relax :-)

I do not think that the law could be approved because of the reasons that I said in the above post and I am very optimist at this regard.
Anyway, I think that an online petition could be done, it could be a good solution IMO.
I think that writing directly to Mrs Grant is just a waste of time... she turns a deaf ear   
Coming from a bigot area I have already had this kind of experience, I can ensure to all of you that however hard you try to explain your points of view, obtuse people do not change their mind.
Furthermore, Mrs Grant finds her decision-making power basing on the fact that, obviously, most of WGs work anonymously and can not demonstrate against  proposed Bill at the front door of the Parliament.
This is one more reason for making a petition
