i'm of two minds on this topic:

1) personal responsibility- we, as adults, participating in a very large world wide online public forum with thousands of topics and members who read, post and/or participate in the many conversations found here everyday have the responsibility to look out for ourselves and do what is best to keep our ourselves 'safe'. as adults, we need to be mature and sensible enough to be able to understand ourselves enough to know when a discusion topic may or may not stir up some strong emotions. if you know a topic is gong to cause distress, or is going to bother you, then perhaps it is best to do some personal self care and either take a break or avoid those topics that are known to or may cause such distress.

2)i'm in support of sub-forum if it will help maintain the continuation of some very informative constructive conversations, support, and important topics from being locked down by the moderators because of some members who become upset and began to detract an informative and/or supportive thread into what feels more like a squabble among five year olds in a sand box. this very topic tends to result in some very uncomfortable thoughts and feelings for quite a few people which often leads to some very passionate, sometimes personally harmful to others, emotions emerging and becoming intertwined into the conversations and the detriment of the thread. i would rather not witness or be involved in those kinds of 'debates' and often find it disheartening to see this kind of behaviour happening among fellow support forum members.
