Glad someone got a giggle, practical 
I'm going to try and write down my conclusions to this hooha. If this gets deleted too, I obviously have not yet got the knack of writing a dispassionate argument. Let's take it as read that the way I put it before was too, ahem, forceful for some readers though I was only saying what I think.
So! I've come to the conclusion that although, as empirical evidence shows, there exist on Gransnet threads where, by agreement after a desire for no arguments/disagreements/"argy-bargy" has been expressed by one or more posters, the thread remains non-argumentative but rather simply supportive of the various posters, or of some goal they are aiming at, for some reason this could not be allowed on this thread.
Put baldly as a matter of democracy on GN, I understand the idea of threads being all inclusive. Empirical evidence shows though that there is in fact some of what might be called self-selecting in threads and I think that's all this thread was really asking for. Where my understanding starts to go awry is that when you take into consideration the fact that there were several other threads where argument on the subject of UK EU membership was already underway and thriving, why did some posters feel the need to argue on this one as well? I'm tempted to think (without looking to check, I have to admit) that argument/discussion had got a bit stale on the other threads but that this one provided attractive, fresh 'bait'. Part of that thought also wonders (also without checking) if perhaps the reason the discussion had got a bit shall we say one-sided in those other places might be because people like me had felt overwhelmed by the sheer 'bombardment' (others used that word) and wanted to go somewhere where they could discuss the reasons for their decision about the referendum vote in a place where, they felt, people understood where they were coming from.
If my surmises about the other EU Ref threads are wrong, and discussions are in full flow and jolly interesting, then my lack of understanding of why anyone felt the need to argue on this one is complete.
I'm keeping a copy of this in case it gets deleted. Paranoid!? Who, me?
