I respect beliefs that aren't pushed on someone. For example, I have a working idea of the universe with regards to sprituality that involves neither science nor religion. I don't push that belief on others, I only offer it when my opinion is asked, and I discuss it with an open mind towards the idea that I might be completely wrong. That type of belief should absolutely be respected.

You can’t really respect another person if you disrespect his/her religion..

Math is not that easy. How does something like eg. Group Theory fits into this “definition”? And yet, it is useful to the real world.

Superstition is not religion.
