The kind of secularism promoted by "Reddit atheists" does not reduce the belief and support of traditional Christian or Western values or Eurocentric thought, in fact it reinforces them, because now people are free to believe in those values without having to engage in anti intellectual stuff like denying the theory of evolution or the big bang, or believing that mythological parables from the Bible are meant to be taken literally.

surely it's easier to break people of these beliefs when they don't think it's ordained by the omnipotent creator of the universe.
