An important thing to remember in conversations about triggering, which people on the internet, especially redditors, like to refer to as "muh feels", but it's not about feelings or mood largely. Survivors of rape, or assault, or war, or whatever causes PTSD, or various other trauma-induced mental issues, have a serious risk of dissociation wherein, among other problems, a continuity of consciousness is broken. Now if you're reading an article at, say, your office, and you have issues with PTSD from your rape, reading a detailed description of something similar may cause you to dissociate. And this is just one of many issues that could arise, that are simply solved by adding something like "warning: graphic content regarding war trauma". This is something that causes no harm to the writer, or the unaffected people, but means a great deal to a victim, so they have the right to choose to read it or not, or save it for a more appropriate time.
