I sometimes find it difficult, as a follower and occasional contributor to the LOC, to quickly and confidently distinguish legitimate opinion-based argument from sterile forms of argumentativeness, correct information from incorrect information or (heaven forbid) wilful misinformation, and legitimate complaints from generic rants.
I think, Renato, you are going to get this on any forum. The LOC is far better than many I have used in the past. The moderators are keen to try and prevent this. Some feel they are too quick to jump in. However, if posts breach T&C guidlines, then there is not excuse.
We must accept that people on the forum will have different opinions, some of them entrenched. I am pleased when debate gets heated that moderators step in to defuse / end a situation developing.
Here on the LOC, we are far more civilised than other car forums!
