Many thanks for taking the time to reply @henddraig
I just couldn't follow your link between not being rude and "brexit" and "he-who-shan't-be named."
I agree, of course, that disgreements and misunderstandings can and should be resolved by discussion, but I much prefer to do this face to face. In my long experience of using the internet and its precursors, I have very rarely found that issues can be resolved or clarified via digital media. (Witness this post )
I have far more often seen prejudices reinforced, hatred promoted and inanity amplified. (Which, to my mind, is more likely to lead to disastrous voting)
I fully realise that my opinion is not shared by everyone or perhaps anyone, and I realise also that my jealous view of this forum as a haven from contention may well be a minority one. If I'm in too small a minority, I'll do the honourable thing ... again
