On a personal level, I find that kind of ignorant judgment quite offensive. My Druidry has nothing to do with Wicca, and should not be lumped in with it, for one thing. I also find it offensive as a general rule for people to judge the motives and thoughts of entire groups of other people without any actual knowledge. I am a Druid, and your friends apparently made sweeping judgments regarding my decision as to my faith without ever knowing me or anything about what I believe.
I am not a Druid because it is novel, exciting, or unconventional. I am a Druid because my people are Druids and have been for a long time, and because I have experienced profound beauty and strength connected with my gods, my ritual, and my practice. My Gran brought her Druidry with her from Wales when she came over to the US, and taught me without brainwashing me (in stark contrast with the brainwashing my fundie Christian parents tried giving me). She taught me to observe closely what went on around me in nature; human nature as well as the wider natural world. I learned that art and story as well as all living things are sacred; that all life deserves my respect. And many other things.
I'm a Druid in the 21st century. I don't dress up in robes and carry a sickle into the woods with me in search of mistletoe. I don't indulge in farcical activity you might see on network television involving pentagrams and candlelight. I apply my Druidry to every aspect of my life always; as a mother, a lover, a student, a nurse, a friend, and so forth. My faith complements my work in medicine; I never sacrifice scientific knowledge to obscure ritual practice.
My gran taught me this: Druidry is ancient, yes; but it is also still alive. The only way an ancient thing can survive is that it learns to adapt, to change with its environment. So no, I am not a Druid priestess like the black-robed banshees on the Isle of Mona who tried in vain to repel the Roman army. But I am a Druid who values life, who sees no division between sacred and profane, who applies science every day and equally applies my spirituality every day.
I object to the insult offered to my dignity in the characterization unjustly made by your friends. This kind of prejudice continues to eat away at the world, and when it touches me, I admit freely that it wounds.
