Is Abp. Rowan Williams really a Christian?

Since moving back to America, I have observed quite a few people wearing all kinds of small items (usually bracelets) with the letters "WWJD" on them. I found out this abbreviation stands for "What would Jesus do?". It is a way of reminding people who claim to be Christian about the importance of their religion in making everyday decisions. You are faced with a problem and you ask yourself - what would Jesus do? Now I'm pretty sure members of the clergy shouldn't need little bracelets to be able to think like this, they are supposed to be thinking about Jesus all the time anyway. So I was very surprised the other day when I heard that the Archbishop of Canterbury, Rowan Williams, spoke out in support of the Occupy Movement protesters who argue for higher taxes on the rich and on the finance industry. I don't really know why he would support such a thing, any economist worth his salt knows this kind of motion will cripple the industry, increase intrest rates and prices across the board, and drive jobs overseas. But there is also an important moral question here (which has nothing to do with the Archbishop's apparent ignorance of basic economics).
Namely, the question is: What would Jesus do?
Now I was raised Catholic and I've read the New Testament quite a few times - and nowhere in there did I see any reference to Jesus telling people they should take the property of others in the name of justice. And this is exactly what the new tax would do. In fact, even its proponents acknowledge this. They call the tax the "Robin Hood Tax", and we all know that Robin Hood stole from the rich and gave to the poor (after taking a certain comfortable provision for himself, of course). Abp. Williams should be able to explain to me how he can defend stealing. Thou shalt not steal was still in the Decalogue the last time I checked. Maybe the Archbishop needs to order a little "WWJD" bracelet for himself.
Jesus was a great man, and his followers, Christians, built a great civilization. Christians are generous and they respect human rights, such as the right of property. Christians do not coerce others and they have a respect for the Law (The Law as Frederick Bastiat defined it). This is why their civilization grew so great, it was peaceful and prosperous when compared to other cultures on this Earth. Jesus told others to give their property to the deserving poor - he did not instruct anyone to steal in order to support themselves or others who had less material wealth. Jesus was the patron of beggars, not of robbers. I hope all Christians who still claim to be faithful to him remember this one day.

To quote the Jesus himself: "If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me." (Matthew 19:21).
Sacrificing oneself for the sake of others is often a great virtue (when not taken to extremes). But sacrificing others for the sake of the poor is akin to human sacrifice, something Jesus would never be able to condone - he was a pacifist.
