Each thread is a separate conversation. There are so many threads that to have read all of each of them would take all day, and even if you managed that marathon, remembering who said what where would take an excellent memory. Speaking about their problems on one thread (and receiving supportive replies) doesn't inform a different set of people in a different conversation in advance that if someone seems to be often posting aggressively, they should be excused because of their circumstances. As I've said before, EVERYONE has problems.
I read several of Shanma's posts on the lines that she could say whatever she wanted to, and she went on to do so. Then she started this thread which carries that theory on. It is not in the least surprising that she got some negative comments (other posters than her wanted to say whatever they wanted to). I've not been reading the latest exchanges, but it would have died down after the first day without further stoking by Rigby46.
