It is the principle! That such an organisation which, whether we agree with it, approve of it or not, holds such a position in our society and politics, can appear to reject women as worthy of high office is appalling.
It has, as was said in The Times today, put itself in the position of the Labour party when it allowed a vocal minority to hold sway, while the middle of the road majority did not rise to the occasion. The dioceses did not work hard enough to ensure the loonies (the evangelical right, I suppose) were kept under control.
I hold no particular brief for the CofE, but the wider implications of all this infuriate me.
