Discusing issues of Druidiry or Neo-druidry are complicated by the work of one man, Iolo Morganwg. Born Edward Williams in 1747, Iolo wrote, forged, and collected many of the sources together that formed the basis of modern Druidry.
Personally, I don't find his mythic misrepresentations any more troubling than Gerald Gardner's mythopoetic claims for the founding of Wicca.
When we discuss mythopoetic truth, we are not dealing with rational, factual truth, but whether or not the imagery resonates with the deeper aspects of our nature.
All words are made up, and spiritual language doubly so. That doesn't make it any less true, but it requires us to do a different kind of work to verify it.
Protestant Christianity has damaged our collective understanding of spiritual truth. Its belief in the inerrancy of Scripture and its fetishism for ancient truth has translated into a practice of proof texting and fetishizing of indigenous belief and practice in many of us who seek out spiritual truth.
Neither antiquity nor novelty of belief or practice makes something true or false. All beliefs or practices were novel at some point. The questions are: do they resonate, does it work, and does it persist. If it passes all three of these questions, then the final discernment comes through asking why does it work and does it foster the principles we seek to foster.
Those last two questions are vitally important. Racism, sexism, and queerphobia resonate with a lot of people, they work for them as rallying cries and focal points of meaning, and they are stubbornly persistent. It isn't until the last two questions that they fall apart. Why do they work? Racism, sexism, and queerphobia resonate with people and work to foster community through granting a sense of superiority and a collective target. They absolve people of the duty to examine their own faults because the target of hatred are the root cause of all evil, trouble, and grief. It this way they violate our basic principles in that they foster hate and strife. They twist reality to create scapegoats so people don't have to practice teshuvah and tikkun. If we believe that God is love, wisdom, creativity, and justice, then racism, sexism, and queerphobia violate all of those principles, so they must be rejected.
I am not say this to argue for a reclamation of Iolo Morganwg, or to excuse his work or his methods, but to explain the methodology used in reading his work. It is important for us to look into the origin of these ideas so we can investigate how they three important terms came into use and to examine them.
Iolo Morganwg's seeded many ideas into modern Druidry. It is vital for us to recognize that these ideas are not ancient because we should know where the ideas come from. It is also important for us to see how these terms were originally used so we know the influence people like Iolo Morganwg have on our present beliefs.
