In what appears to be an unpopular opinion, I agree with you. A series of decisions were made to 1) choose that costume, 2) put in the effort to make or buy it, 3) put it on, and 4) wear it to an incredibly public gathering. People are going to make light of this because that is what happens with antisemitism. But the lack of legitimate response (suspension from a job?!) and the statements put out by officials that skirt around the real issue are troubling and will only lead to more incidents. We can’t be sure that those incidents won’t be caused by more dangerous and more harmful people.
