In the Obama administration, there are people who know that the Iranians are anti-Semitic, but they don’t know what to do with that fact and put this mental derangement on a distant shelf. They negotiate with the Iranian leaders, as if anti-Semitism was some odd quirk, instead of what it is, a core element of their mental architecture.
There are others who see anti-Semitism as another form of bigotry. But these are different evils. Most bigotry is an assertion of inferiority and speaks the language of oppression. Anti-Semitism is an assertion of impurity and speaks the language of extermination. Anti-Semitism’s logical endpoint is violence.
Groups fighting anti-Semitism sponsor educational campaigns and do a lot of consciousness-raising. I doubt these things do anything to reduce active anti-Semitism. But they can help non-anti-Semites understand the different forms of the cancer in our midst. That’s a start.
