WC: After re-reading my posts last night and sleeping on the issue and waking in a better frame of mind today, I concede that the tone of the post was both petulant and un-necessary. If the tone of the post caused offence, which was not my intention, then I offer an unreserved apology.
There are a number of issues, which while not well made, are valid, and I will come back to them at a point in the future because I don't think it appropriate to do so now, because if an apology is due I don't want the argument to detract from that.
