Sexual assault is always totally unfunny... regardless of the status of the victim.
We can differ on the matter of gender identity, but please, let’s not make light of sexual assault.
(A) The story was a false charge alleged and the police/school officials seem reluctant to prosecute the accuser, instead attacking the class of "aggressors" with more political re-education.
(B) Putting a member of the opposite sex into male washrooms/showers/lockerrooms is asking for trouble (it does not excuse an attack but is counter to rational thought).
(C) Few people express concern for the victims of prison rape. Prison rape jokes are celebrated in the media (tv, movies, and even on FR).
Nowadays sexual assault is overused. In the military sexual assault can mean anything from rape to texting pics. Any incidents that involve a male and a female seems to be automatically sexual assault.
A soldier touches his female buddy with his rifle, sexual assault. Stuff like this and more.
