For me a lot of my very negative reactions to safety tools and conversations like this one stems from my own experience with mental health issues and mental health issues in my family. I am very much coming from the opposite place of 'toughen up buttercup'. If someone in my life is going through a mental health issue, I am going to help them and be supportive. But being supportive doesn't mean you bend the world around their issues (that can actually do a lot more harm sometimes). It is complicated and it isn't something that a checklist from an RPG publisher or a sidebar can deal with. And I also think a lot of these conversations just further stigmatize people with mental illness, with phobias, etc, because it makes it sound as if things that make them slightly uncomfortable completely set them off. And again, can't emphasize this enough: triggers are not as cut and dry as 'person is set off by the color green, so don't mention green'. All kinds of things, often very nuanced, subtle things can trigger an episode (including thoughts in their own mind going from point A to point B to BAM!). This isn't something a game group is equipped to handle because they have a checklist and sidebar.
