She wasn’t mentioning the Gad issue, but the reaction to him. Gad said nothing about black people, and so the criticism should been directly related to Gad (Professor Gad you are a jewish racist, or “Mr. Gad, you don’t know about the accomplishments of great Muslims; it’s not all about Nobel Prizes” or whatever). Instead this man who react dragged in metaphorically black people to comment on Gad instead of directly commenting on what was in Gad’s graph.
