By this logic, everybody should overlook the Shoah since some of the victims were heterosexists and cissexists:

In the Lichtenburg camp, homosexual and Jewish prisoners were temporarily put together in the punishment company. The two prisoner groups were also grouped into the same work details that had to perform particularly heavy or filthy labor, like the cleaning of cesspits and sewers in Lichtenburg, or the gravel pit and the road roller in Dachau.⁴¹ In enduring these harsh conditions, homosexual prisoners could expect little or no solidarity from other prisoners.

What is more, other prisoners, and here the Jews were no exception, reproduced the stereotypes ascribed to them and often saw homosexuals as gossipy, mendacious, and enslaved to their uncontrollable sex drives.
