I have just read through this whole thread again and, for the record, there doesn't seem to be a consensus. Rather, there is a considerable range of views – some quite extreme, one way or the other, and a lot in the middle with plenty of provisos. And, like many other threads, masses of stuff that has nothing to do with the subject. As we are once again getting hints that people won't post their views because the majority won't agree with them – a fairly feeble viewpoint in the first place – please note that there does not seem to be a majority to disagree.
