Today is Yom HaShoah, the annual commemoration of the six million Jews murdered by the Nazis.
The fact that it happened over seventy years ago makes it no less relevant.
The fact that the Nazi’s allies, enablers and successors are not so silently waiting in the wings to repeat the crime makes it more relevant.
Observe a moment of silence in their memory.
Do it publicly and if questioned, explain.
If challenged by deniers shame them.
