I tend to use the broad term of religion as such as well. In
   this case, I've been keeping it restricted to "world religions"
   but generally, I agree with that. In that way of thinking,
   secularism=religion, idealism=religion, mathematics=religion,
   logic=religion. Not everything of course = religion, but when it
   becomes an over-reaching cause - the God of your existence, it
   becomes your religion.
