Some or even many of these researchers are researching what they and/or loved ones have endured, and they are researching to understand more what happened to them & to help others. By the way, would Heat Street mock (for example) Holocaust survivors and the descendants of Holocaust survivors and victims whom needed counseling and/or to leave certain lectures?
Even imagine, for example, a doctoral student whom is attempting to finish the degree that she forcibly had to suspend do to the Nuremberg Laws. While she sits in a lecture about Anti Semitism throughout history, she sees a picture of her twin sister while the pictorial slideshow plays. Given that her sister was among the Mengle Twins whom were murdered, she has flashbacks to when she was one of the twins whom "Dr." Mengle exploited and her twin was murdered shortly thereafter.
Also imagine that she sees a picture of the crematoriums, and flashes back to when her parents were burned alive in the crematoriums (This really did happen to Elie Wiesel's father on January 29, 1945, per "Night": "They must've taken him away before dawn and carried him to the crematory. He may still have been breathing.").
If she is a "snowflake", perhaps she was a cold and icy one whom (figuratively) melted in her own tears (tears that would not come before, since she had held them back).
