The pendulum – life is really a pendulum – There are many deep Kabalistic doctrines / reasons but a simple example – First people were "noble" savages, creating holy war after holy war, for example between factions of Christianity, not to mention just conquest for fun – then after two stupid world wars, they woke up and introduced a love/ open policy – Quite remarkably ( I believe the first time in human history) western nations had a clause of allowing in anyone who could claim political persecution – But then an arrangement had to be made, for as we in the west who had this awakening that war is stupid, those influenced by the koran to “murder your way to heaven” obviously did not; hence far from being hate-filled, when the Brits did Brexit and Americans voted Trump, it is simply an adjustment – for our discernment is good
