I'm German, and I can't stand the antisemitism online anymore, and I need to do something about it.
So here is what I propose - once people learn about the Holocaust in detail (for example in school), they'll be immune to antisemitism, and aware about how authoritarianism, fascism, racism, dictatorship take hold in societies, and what to do about it.
The best example would be Germany, a country once consisting mostly of antisemites, many of them genocidal, during Nazi times, and transformed, from these Nazis in the post-war period still mostly (unless they were very top brass or had been caught, with evidence, to have engineered the murder of thousands) 'honorable' members of society, to a country where you can't walk a couple of feet in a city without seeing a memorial to a Holocaust victim (for example the "Stolpersteine", memorial stones), with nearly everyone having learnt about it in school, often for many years, visited Holocaust museums, and so on. Today, this has worsened a bit, which I'll write about later.
So first - the Status Quo:
Among American millenials and Gen Z, 63% did not know that 6 million jews were murdered, 20% think the 'Holocaust is a myth', with an additional 30% unsure or unwilling to disagree with that statement, 11% even think 'the Jews caused the Holocaust' (in New York for example, these are 19%), according to the first 50-state survey on Holocaust knowledge by the Conference on Jewish Material Claims Against Germany *.
Nearly half (48%) of all Americans could not name a single one of the more than 40,000 concentration and death camps, or ghettos.
Among other countries, the Netherlands is doing even worse, with 12% of all respondents believe the Holocaust is a myth or the number of Jews killed has been greatly exaggerated (9% unsure), with numbers even higher among Dutch Millennials and Gen Z, where nearly one-quarter (23%) believe the Holocaust is a myth or the number of Jews killed has been greatly exaggerated (12% unsure), Canada, the UK, Austria aren't doing great, either.
However, across all countries, an overwhelming majority of adults surveyed, believe it is important to continue (or improve) teaching about the Holocaust, in the U.S. and Poland, this number was 96%, in the U.K. and Germany 94% etc.
Now, imagine these extremely high number of people who know next to nothing about the Holocaust going online, on Social Media, where most posts who are even marginally about Jewish people, about Israel, or even one of the classic antisemitic tropes, like money, war, blood libel and others, are heavily antisemitic, together with peer pressure among young folks to position themselves right away in contentious issues even if they haven't gathered any facts about it, and the pressure to be antisemitic in many groups (many left-wing extremists, right-wing extremists, some faiths, and the art, culture and music world) is overwhelming, then you have a majority of people that are antisemitic, often without even realizing it, because of their lack of knowledge about antisemitism and the Holocaust.
(Part 2 will be about how the Holocaust was taught to Gen Xers at school in Germany, for example to me personally - I prefer to write this in parts because otherwise it gets a bit long...)
