nightowl There are a huge range of threads on Gransnet and most of us, ignore some, merely follow others and participate actively in yet others. We all have our likes and dislikes.
I see very little nastiness on the political threads, heated debate, yes, some members with deeply entrenched views, yes, but if you want to see political nastiness go to almost any other mainstream political thread and what you read there, the insults, invective, personal attacks, makes us appear like a convocation of kittens playing with knitting wool.
I suspect that some members have perhaps not been in situations that involved robust arguments about views and opinions between people who are generally good colleagues/family and tend to see any strong exchange of opinions as a sign of personal animosity when it is nothing of the sort.(DH is one like that).
