Belated response to Dick correcting me:
"Groucho Marx, Not Mark, Richard,I am not against anything, apart from being misquoted ..."

The "Mark" was of course a mere typo, of which one finds many here. (One other board that I use allows one to go back and edit one's own posts. That facility doesn't seem to be abused, but it could be a double-edged sword, and I'm not suggesting it should be introduced here. In its absence, however, we have to put up with silly mistakes, our own and other people's.)

As for who's against anything: I accused no-one in particular. I say only that some of us seem to expend a lot of effort in disagreeing with what others have said, or our interpretations of what others have said. Healthy debate is fine and dandy (e.g. in the present context "Your experience tells you X, but mine tells me Y") but it too easily becomes heated.

But this isn't the first thread where that has gone on, and I'm sure it won't be the last.

Meanwhile, we've also had a lot of interesting and relevant quotations, for which thanks.
