If you think materialism leads to nihilism you don't understand materialism.
You are talking to me on a computer powered by solar panels. Don't pretend you are rejecting modernity and following a biblical lifestyle. You a picking and choosing what you want to believe is good and bad about modern society using your own judgment, the same as I am.
That's fine. I'm just not in denial, I face the personal responsibility that those judgements bring head on. You point to a source outside yourself, sometimes when it gets you the answer you wanted anyway.
