Contentiousness was my point, db. Life is full of contentiousness. There is nothing wrong with contention per se. I doubt if a subject on this planet contains absolutely no contention should people actually volunteer their real opinions about it. Even pet cats. Yes this thread and many others are full of contentiousness. So what? Nobody need join in, or even carry on reading, who dislikes it.
And now I will be told off and disapproved of for speaking in favour of contention.
Nota bene: I have no objections to pet cats. I did read a list of things really Green, planet-friendly people shouldn't do recently though, published by some green group, and having a pet was one of them. I can't remember if it was emissions or destructiveness or something else that was the problem. I just rolled my eyes and moved on.
