Some people capitalize Pantheist and Druid. I think it is because they see these things as specific religions, so they capitalize them just as they capitalize Christian or Catholic. I see pantheist as parallel to atheist, polytheist, and monotheist, which are not capitalized. I see druid as a bit more complex. I think that to say someone is a druid is like saying they are a vegetarian or an animal rights activist or a pacifist, so it is not capitalized. However, I think it should be capitalized when used with a narrower meaning, such as to say someone has attained the rank of Druid in the Order of Bards, Ovates, and Druids.
So, I call myself pantheist and druid without capitalization. I will not criticize anyone who uses capitalization when applying those labels to themselves. I think we all have the right to choose our own labels.
But am I a pantheist druid or a druid pantheist? In such a phrase, the first word is an adjective describing an attribute or state, while the second word is a noun, identifying what a person is. For example, a person may be described as a wise woman or a happy child. By this reasoning, I label myself a druid pantheist. A pantheist is what I am -- I cannot change on a whim my fundamental beliefs about the nature of the world. Druidry is a practice in which I choose to engage, but which I could at some time choose to stop doing.
