There are a number of errors that I see in this post.
Magic is not a religion.
Magic is simply an art and a science. One can be of any religion or of no religion at all and still practice magic. While there are some religions which do use magic, that does not make magic a religion.
Wicca is not an ancient religion.
Wicca was founded by Gerald Gardner, a British Civil Servant, in the 1930's in England.
Pagan religions are ancient, but remember that there is no religion of "Paganism". Paganism is an umbrella term which covers a wide variety of different religious practices with very different beliefs. Not all Pagan religions include magic. In fact, in Asatru (the religion of the Vikings) magic was frowned upon as being unmanly.
Wicca is not a religion of love and protection.
Wicca is a fertility religion where our ethics ask that we live gently on the Earth. But Wicca does not forbid doing harm if the situation calls for it. The idea that Wicca is about "light, love, and unicorns" is the result of poorly written books that are trying to make Wicca seem as though it is perfectly harmless. Traditional Wiccans do not hold those beliefs at all.
Rune casting is not a spell.
Casting the runes is a form of divination. Runes can be used in magical workings, but casting the runes isn't any sort of spell.
