Eric Clopper was a Jewish American worker at Harvard University, who a couple of years ago gave a speech on stage about circumcision to a crowd of students and teachers. The presentation was called "Sex & Circumcision: An American Love Story" and the video itself is over 2 hours long. In case you were looking for the timestamp of the moment above, it's at 1:59:57

In the video, Eric slams every form of circumcision and genital mutilation performed on children, listing the effects and talking about his personal experience on the subject. His presentation got very popular, but unlike others who opposed Judaism, he was not endorsed by the far-right or the alt-right (him being Jewish would have turned him away from it anyway), and to this day he remains with the satisfaction of getting it all off his chest. Currently the video is still up, and so is his channel, however the presentation got him fired from his job.

I honestly do think that the widespreadness of circumcision is really terrible. I understand allowing people to practice their faith in the way they want, but I don't think that it should give people the right to mutilate children's genitals.
