To expand a little on this topic.
Saying how you're an atheist for organized religions is easy nowadays. But are you able to stretch that idea to other topics as well?
For me atheism is much more than not believeing in a god. it's also not believing in positive energy, horoscope, power of crystals, power of the moon, karma, reincarnation, tarot reading, ghosts, etc.
I think that in the absence of classical religions, the modern human had to replace it with all this new age nonsense to fill the gap.
