Reading the mermaids recent tweets, it would appear that charities come from a strong emotional point of view of stopping the thing that they are against/afraid of happening at all costs. It is not a reasoned view point. If they are doing the work of government departments, they need to have a much more dispassionate overview and see all sides to serve everyone properly.
Government seems to be relying on their opinions and research without looking further.
Emotional involvement is a good thing for raising money, but not for policy formation.
It is the same with a particular cancer charity, built on the death of one person, that wants to prevent that particular death from happening to anyone else. This is now used by the health authority for education resources etc and now tries to influence policy where it disagrees with the well considered government stance. They do not see that their view is not good for everyone and won't listen to critics.
I can think of other examples.
