The simple lesson of life – and we have 5773 years of lessons to look back, is this – as God says to us 3325 years ago in the Torah: realize that the world is a mixture, in it there is both light and darkness, life and death, and choose light / life! – practically this means, life is a very simple choice, light / life, darkness / death! it always has been this choice and it always will be and if you see people who are not in life and light, know beyond a shadow of a doubt, they are in death and darkness, aka Hitler, antisemitism, radicals and anyone who has hate in them.
