Maybe the Green Party new policy has been counter productive (and always was going to be counter productive) in that it has moved the discussions to be about definition of terms, exceptions to classifications, etc. rather than focusing on the plight of the Palestiniane in Gaza and the West Bank and adopting policies to help then and establish some long term peace.It's impossible to have a fruitful debate where the central terminology doesn't have an agreed definition. The problem here specifically is that there are two broad definitions, where one of them says that all Zionism is racist (e.g. Green Party motion), and the other (see Behr, Aaronovitch & Sugarman) says that Zionism includes racism.
Whatever the right or wrong of the policy, ill thought out and focusing of political games rather than achieving anything.
