Oooh, ooh, ooh can we debate the meaning of the term irreligious
*sorry*
On a serious note, I'd say I am somewhat irreligious. For me, I'm taking that to mean I have no personal use for the doctrines, concepts and rituals of religion in an identifiably 'religious' context. I am not irreligious in the sense of being hostile to religion though, and I'm actually quite interested in it, especially from a historical perspective.
I am aware that much of my worldview is ultimately derived from 'religion' as it is ubiquitous throughout our history, and that's what many things we take for granted were ultimately grounded in before they became detached. So that's why I go for somewhat irreligious over very irreligious, even though I'm not 'religious' or 'spiritual' in any way, I can't escape the fact that we've all been shaped by religion.
Religions are just another form of making meaning for ourselves through myths, I'm not sure I can really define them in a satisfactory way. Seeing as we all do this anyway, I'm not so sure there is even much point in trying to decide exactly where religion stops and 'not religion' begins.
There was an episode of South Park called 'The Simpsons already did it', and with most worldviews you could say 'religion already did it'.
