For
me, fear in posting is often directly related to events in my 3D world. While it does feel to me that there are times when people are triggered here and respond based on that trigger and seemingly completely forget there is another poster involved, overall I believe the support here outweighs the arguments (for me).
Sometimes I see the arguing more because my brain is always trying to see safe or not safe, but if I think rationally, I do believe there are heaps more supporting posts than arguments.
For me, anger, etc is a big flash warning in my head that it's not safe. This isn't always the case though (as far as safety is concerned). But, my stuff does get in the way of posting.
At any site, there are going to be disagreements I think and if I add the mental illness element into it, it may become magnified. On top of that, my own fears and triggers hinder my ability to see things clearly sometimes.
I'm sorry you are struggling right now. I hope things settle down for you soon.
