It's actually Gen Z that "needs" trigger warnings--Millennials seemed to have survived without, for the most part (at least in that they generally finished their educations before trigger warnings became commonplace)--but if Parler users were to think something like this they would be...

...right on target with the bulk of psychological research. (See, for instance, The Coddling of the American Mind (2017) by Lukianoff and Haidt, for an overview and a variety of references.)

An appropriate level of adversity does make people strong, and Gen Z is suffering from a high level of depression and anxiety, likely due to a variety of factors including trigger warnings (which simultaneously provokes anxiety and depression on their own while doing little or being actively counterproductive for developing emotional resiliency).

If only Parler users would think something so relevant and well-grounded in reality all the time!
