I was raised sort-of passive Catholic. At 10 years old, I became a Non-believer. 10 years later, I thought of myself as an Agnostic. Another 20 years passed and I was an Atheist.
I now think the label Atheist is too restrictive as it only says I don’t believe in a god. There are many things I don’t believe in, like homeopathy, psychics, angels, magical healing, the power of crystals, voodoo, trolls, ghosts, and a lot more.
Skeptic is not bad, but does have a connotation of permanent ambivalence. The right label, if I need one, might be Rationalist or Evidentialist.
