Reddit mentions of The Rebirth of Druidry: Ancient Earth Wisdom for Today

You should check out The Rebirth of Druidry by Philip Carr-Gomm, Chosen Chief of the Order of Bards, Ovates and Druids. It outlines the history of contemporary druidry and speaks to some of the issues others have pointed out (prejudice from outside, lack of primary sources, discontinuity in the community). It would be an excellent source for you. Some ideas:

• There is prejudice against Druidry as being seen as "not a real practice" or "not a real religion" (although many Druids do not practice Druidry as a religion). The reasons given are the lack of primary sources (first hand accounts, histories and interviews with historic Druids), lack of religious canon (Bible, Qur'an, etc), and lack of a unified organization (hierarchical church, administrative structure, central organizing body).

• Druid traditions are generally built on the idea that it is the indigenous tradition of the Celtic peoples. As such, there is sometimes a perception that it is only for people of a certain northern European ancestry. Heathenry & Asatru have been much worse plagued by this issue, but Druidry has had to defend itself as an all-inclusive tradition.

• Since Druidry comes from a largely conquered people (Rome systematically destroyed Celtic peoples, Christianity mopped up mythologically), many Druids incorporate other traditions and borrow practices from other belief systems to supplement their practice. Many embrace Universalism or Syncretism. This has led to criticism of Druid practitioners co-opting other cultures and beliefs in their spiritual pursuits. Although there is archaeological evidence for the Celtic use of structures like sweat-lodges, didjeridoo-like instruments, and entheogen use, there are some who see this as appropriation. I want to stress that these are broad statements - Druidry is complex and every practitioner is a bit different. Not everyone incorporates or even endorses these practices. But I do see and hear this conflict come up from time to time.

• As far as modern issues that affect Druidry (which is a different question, but may be what you were asking), I would say the primary one is Environmentalism. One thing nearly every Druid will tell you is that their practice is rooted in nature spirituality, or is a nature-based religion. The connection to, and rooting in, nature is central to nearly every practice. Some Druids forgo belief in "the Gods" altogether and merely seek communion with nature directly. Druids have a long history of environmental activism, tree-planting and preservation, what we might today call permaculture practices, and natural living (a useful, albeit broad term).
