When the Holocaust ended in 1945, the world vowed 'never again'.
Over the past few days, we have all watched, shocked and horrified, as Nazi symbols and rhetoric - in 2017 - have been on our television screens and in our newspapers. One can only imagine how the survivors of the Nazis felt as people chanted "the Jews will not replace us", only 70 years on from the Holocaust.
When we teach young people about the Holocaust we tell them that it did not start with the gas chambers, it started with hate-filled words. To see the Neo-Nazi, racist and antisemitic symbols and language used openly in Charlottesville should shock and horrify all of us.
Such hate has no place in our society and we all have a responsibility to act wherever it rears its head. It is not enough to simply be vigilant - in these fragile times, we must speak out and stand together.
We know that when hatred is left unchecked, it can lead to dark and dangerous places. The only way to prevent it is to educate, educate, educate.
