"SYSTEM of belief and worship"

No system - just the answer to one question - 'Do you believe in god or gods?" answer NO - that's it! Nothing else.

No worship

"informal an activity which someone is extremely enthusiastic about and does regularly."

You mean like swimming, watching football, being on QL etc etc etc

I didn't know they were religions?

Gosh, you learn something new every day! :P

Watch the vids - easier to see and hear than write about it here.
