People with traumatic events in their past can often be violently transported back to a harmful time in their life by the mention or depiction of a certain topic which draws too close to home, causing that person severe mental pain and suffering. It is for this reason that trigger warnings, or content warnings, are often implemented before challenging material. For example, stories which may deal with suicide, domestic abuse, or eating disorders may disclose those themes before the story begins to spare those who would suffer from reliving those events.
My question is not whether trigger warnings are valid. They are, and if you don’t think so then this conversation is not for you. My question is: what would be the best way to implement this for comics? The “Mature” label is too broad to be helpful in these cases, and overt specifics may be picked up as “spoilers” for the story within. What would be the most effective, reasonable way to implement trigger warnings in comics?
