Artdecogran, I'm so sorry that's has been your experience of GN.
In my opinion, GN is a snapshot of society: there will be people we like, people we don't take to, people of the same mindset and those who are not, kind people and nasty people, people whose glass is always half full and those who feel that life will always be full of sorrow.
That's just like real life.
I have been at the receiving end of some nasty comments and my life made miserable by a particular poster, however in amongst all that, I experienced great kindness, empathy and support from posters. I have laughed and cried with posters, moaned and groaned with the best of them.
Over time I have made some lovely virtual friends, some of whom I plucked up courage to meet in person and never once regretted it.
When weighing it all up , I decided I was better, with, rather than without GN.
Perhaps you are just on the wrong threads, why don't you give it another chance?
