It is ironical that most people who think they posses strong critical thinking are actually believers in materialism, a philosophy totally refuted by science. If you stop to think about it, it’s “more refuted” than Christianity or even the Church of the Flying Spaghetti Monster because you can’t really refute these things head-on like materialism was refuted through science. You can’t disprove the spaghette monster as clear as materialism has been disproved by science.
Worse than this, many such atheist are religious humanist, believing in doing good deeds and helping other people, ecology and stuff like that despite being atheist, being probably the most irrational people in the world when it comes to views. Religious humanism is probably the most irrational stuff one can believe in.
This religious humanism that has replaced Christianity in the west, if you stop to think about it, is much more irational and empty of any kind of logic than Christianity.
