Johnjohn:

I commend you for at least offering a partially coherent assertion that might have some substance to it. Your colleagues could profit from a study of the difference.

But let me point out that each of the voices that seem to come out of the woodwork on this thread are asserting singular opinions. No-one has offered me any facts to counter the various points that have been made in the links I have provided.

Martin, your contributions are so frivolous and so irrelevant and meaningless that by rights they ought to be deleted, as they are obviously only there to make the thread hard to read. Your conclusions about my attitudes and so on are even worse -- groundless, ill-formed, ill-mannered and boorish, obviously the deep thoughts of a brutish mindset.

Stay well, it may be all you have going for you.
