Thank you Galaxy and Dickens. There are many things on which posters agree and disagree with one another, but it should be possible to do so without nastiness and personal insults. As you and the vast majority of others prove.
There are matters, about which people have strong feelings one way or another. One person's emotional investment in a subject does not invalidate another's which might be in opposition. Our own personal experiences will often drive our feelings about an issue which, I think, is perfectly understandable. If I have strong 'sensitivities' about something, that doesn't necessarily make me 'right' and them 'wrong' for not sharing the same sentiments.
Then there are facts and some posters are very knowledgeable about them in a particular area - you, for example, in areas relating to Law. Comment is Free, but Facts are Sacred (CP Scott, Manchester Guardian Editor, 1921). Sometimes, facts are what matter more than opinions... as Joe Friday (Dragnet 1951) said, all we want are the facts, ma'am. And I've just dated myself by remembering that TV show!
There's also the matter of each poster's posting 'style'. And that causes problems because there are those who take umbrage at the way people express themselves (I've been guilty of that). But it can't be helped, it's the nature of social media. That's why there are rules and guidelines about being respectful, etc, etc. We will never be able to corral people into one single way of voicing an opinion. Sometimes I'm offended by a post that doesn't bother anyone else - and the opposite is also true.
All in all, I think GN is a pretty 'good' social media site, I've seen very few deliberately hateful or aggressively nasty comments - certainly in comparison to other sites where there are some humdingers of comments that are, remarkably, often allowed to remain when they are quite clearly in breach of the 'guidelines'!
