I had to look up 'vile' it seemed such a strong word to use about posts on GN
foul, nasty, unpleasant, bad, disagreeable, horrid, horrible, dreadful, abominable, atrocious, offensive, obnoxious, odious, unsavoury, repulsive, off-putting, repellent, revolting, repugnant, disgusting, distasteful, loathsome, hateful, nauseating, sickening
I haven't seen any posts that meet any of these definitions, yes people argue strongly, sometimes they even swear (shock, horror) but mostly their opinions are expressed quite reasonably and without personal criticism. There are threads with strong discussions and others with supportive and encouraging comments. You can choose. Personally I can only stand so much niceness, but I wouldn't want to stop others from indulging.
