You absolutely cannot prevent the addressees of trigger warnings from freaking out and experiencing “crippling anxieties” and “violent illnesses”. There is nothing any layperson can do to prevent that. You can’t do that with trigger warnings, you can’t do that through not mentioning certain things, you simply can’t do anything about their feelings.
Their reactions are not about you and you don’t control them in any way. This is why these warnings are counterproductive. They promise what you can’t deliver.
The best strategy is to refuse to engage with these forms of extreme self-manifestation in any way.
People keep saying, “But what’s the harm in a simple short statement?” What’s the harm in letting an epileptic believe that you can prevent him from having a fit in your classroom? What’s the harm in letting a bipolar person believe you can prevent her from having a manic episode during a lecture?
The harm is that people begin to think that the origin of their illness is you.
