Being nature oriented, there is this look towards the female as being most in tuned with nature as she mirrors many of natures qualities quite well. It is no wonder, then, that it was quelled during the patriarchal institutionalisation of Christianity, and yet a recent resurgence as women gain equality once again. A link to feminist literature is also no surprise, as nature-centred religions are exposed to worship the female and her power.
There's an openness to the religion based on the fundamental principle of the Golden Rule. There is no control or proselytising as in some other religions. Wicca is more of an attitude of being in tune, and at balance with nature, and the spiritual world. What is, is right. No one tell another what to do, or how to believe. Do whatever you want, but do not hurt others tends to be the standard outlook from the religion.
