This is a forum. I don't particularly see it as a place where I have any obligations other than to be civil. My one obligation is to take care of myself in whatever way I deem best. I don't have anyone on my ignore list, but I don't tend to be triggered by posts. Some people I don't bother to read because I find their perspectives off the wall and delusional; no need to try to reason with someone who is entirely delusional or psychotic. Just do what you need to do for yourself.
