Pagan is a catch all term to describe either religions worshipping deities other than the Abrahamic God (and as such, Hindus could rightly be called Pagans, as can a vast amount of other religions) or it describes the religions of ancient Europe, particularly the religions of the British Isles. Wicca is a form of Paganism in that it both involves the worship of non-abrahamic deities and because it is heavily inspired by classic European religions.
The term "Paganism" can be applied to Wicca, Kemetic Reconstructionism, Hellenic Reconstructionism, Heathenism/Asatru, Discordianism, Shamanism, Daemonolatry, Hinduism, Shinto, Druidism and even Diabolism. While the word "Pagan" can correctly be applied to all of these radically different belief systems, many people prefer to call themselves by whatever title they feel is a more accurate description of their beliefs or simply whichever title works for them (which is why I suggested the mirror excercise for you).
So, to put that in terms my feble brain can understand D) paganism is the "form/medium" and wicca is the "genre"? It's basically an umbrella term?
I'll have to research some of those religions you mention more closely as I don't have a great knowledge of some of them.
Thanks again, Shyanekh, you've given me more to think about.
