Wiccans look to and revere nature as the wonderful and diverse thing that it is. Homosexuality is inherent in nature and has even been well-documented in studies done investigating it within 500 different species and has been observed in more than 1500. (There is currently a installation exhibiting this at the Oslo Natural History Museum in Norway titled, "Against Nature?")

So, while individual opinions may vary, I think you could safely say that, even without documented and scientific proof, most Wiccans are openly accepting of homosexuality as a part of the natural order of things.
