I’m not really sure there are such things as “Western Values”.
There are Christian values. There are British values. There are Northwestern European values.
But “Western values” says too much, and too little at the same time.
Western Civilization is a combination of Biblical morality from ancient Jews with scientific and engineering values from our brutal pagan predecessors.
Dropping Biblical morality by definition destroys Western Civilization. And look at contemporary American blacks to see what happens when science and engineering are denigrated along with the abandonment of Biblical morality. The whole culture is headed where American blacks are now.
