It all boils down to one thing...your personal truth. That's something only you can figure out for yourself.
Wicca is duotheistic: all gods are one god, all goddesses are one goddess, and together, they are one. Wicca is a religion, it has it's own set of beliefs, ideologies, and doctrine. So, in the strictest sense, Wiccans are duotheists, but have the freedom to decided which cultural pantheon they feel most attuned to, and therefore work with.
When I was initiated into my Gardnerian coven, I was never wholly comfortable with duotheism. To me, it's like saying all men are one man, all women are one woman. I was, and still am, more comfortable as a polytheist, someone who believes in a whole host of gods and goddesses, separate entities connected by divine energy, just like all human beings are separate yet connected together energetically. So, over the years, this personal belief, as well as many others, led me to move away from Wicca towards Druidry as a spirituality that works better for me, that fits in with my personal truth much more easily.
For many decades Wicca was a very secretive religion, few books were written on the subject. Then, in the late 80s into the 90s, it's popularity exploded and a few moderately good books became available. Eventually, all the fluffy books I mentioned in my last post came on the scene.
The problem with these moderately good and fluffy books is that somewhere along the way, the idea that Wicca is whatever you want it to be became a very popular notion. I mostly blame the secretive nature of the original practioners of the religion. Misinformation abounds whenever you have secrets.
The fact is, Wicca is a religion with it's core set of beliefs, duotheism being one of them. If that doesn't work for you, you can always keep searching for a Pagan religion or spirituality that fits you better.
I'm sorry, but I'm going to have to diagree with czarodziej's recommendations. Wicca is a religion that does not pre-date the 1940s, although Gerald Gardner did take the fragmented pieces of folk belief and practices his group in the New Forest area of England were practicing as the basis for his religion. He added to those bits with the help of Aleister Crowley (the Wiccan Rede), Doreen Valente (much of the poetry you find in the rituals), and Ross Nichols (the seasonal celebrations). The young age of Wicca does not invalidate the religion, the age of the religion, spirituality, or system of belief does not affect it's effectiveness or meaningfullness to the people practicing them. For many years it was in vogue to create a false history of Wicca, one that stretched through the ages, an unbroken line of Wiccans meeting in secret for hundreds of years. The fact is, this is not so, and today we know this.
Don't confuse witchcraft (a system of folk magic) with Wicca the religion, they are two different things. Magic is an auxillary practice that is in harmony with the ideology and practice of Wicca, but they are two separate things. I'm not saying that czarodziej's recommendations are worthless, they're not, they just don't reference Wicca.
