How to tell – from when Adam ate that fateful fruit – as Kabbalah teaches, light and darkness hitherto had been in different realms – but then it intermingled, black and white became grey – those who subconsciously are motivated by hate, cry they are motivated by oppressing oppressors – as we see, the rallying cry of terrorists (quite successful – 30,000 otherwise normal people have joined isis, with millions supporting,) “black lives matter” (the most hate filled divisive movement in America – at least in terms of its numbers, for at its core, it is evil – for if truth is, that blacks and whites are equal, than shaming whites is equally evil – particularly when most whites are not racists, and most black lives are taken by blacks – the list is endless – so the one way you can tell – is sensitivity (namely, all goodness is compassionate, and all cruelty is harshness.)
