A worldview is not a mere passive view, an act of looking at something, which might be suggested from the word, but actually a game plan for shaping it.
Christianity is the religion of whites and Christianity promotes an anti-racist worldview, which means that, with rare exceptions that were vigorously suppressed, the historical game plan of whites has been to deny the importance of biological race.
As their technological culture has now expanded to include all the races of the world, it’s quite obvious that the result has been and will continue to be to increase race mixing, and accelerate their own destruction as a race. As part of the game plan, it was easy to see this coming; but the problem was, with such a worldview, nobody really cared. In fact, they still don’t.
Whites value their technological culture more than their race, and because of this worldview, can’t see that the two are interconnected. This Faustian hubris is one of their defining characteristics and could well lead to their undoing. It’s possible that technological civilization may be able survive the demise of its founding race, but it seems at least equally likely that a permanent collapse may result. It’s the gamble of the ages!
