Papaumau, whilst I respect your views and ideals, I suspect that you are in a minority on this issue, which is another good reason for having a better system of assessing public opinion on this and many other issues, Immigration, the EU, Human Rights act, etc, and then for the government to ACT on the information and not as they do now, stick two fingers up and say we will do what we want, even though they are elected and paid by the taxpayer to reflect the wishes of the electorate.
As for charitable donations, I will and do support the ones I feel strongly about and I do not want anybody, least of all politicians to decide for me, who I should help with my taxes, anybody that wants to support overseas charities can then do as they wish
