he made his statement public
if someone is comfortable saying "I don't want to work for a Jew" then he should be comfortable with the consequences of that statement. He wants to claim he is a victim because he didn't want other people to know his decisions are driven by anti-Semitism. Play stupid games, win stupid prizes.
I can't compare the relative impact so I won't try. I appreciate what the employer did as it serves 2 purposes -- to teach younger people of the consequences of their actions, and to warn other employers that this person lets hate drive his decisions and would not be a good, professional choice for anyone. If someone applied to my workplace and refused the interview because he is an anti-Semite, I would certainly contact similar companies and caution them that they might want to stay far away from this applicant.
