Tarren Renn (they/them) has been pagan for over 30 years. While most of their study was as a solitary practitioner, they studied at various schools and have earned 1st Degree in two different Wiccan Traditions. Both of these Wiccan Traditions said they were very open to people who were transgender, but their experience in working with them showed that the Wiccan Traditions were too focused on the binary of male and female.
As someone who is transmasculine and nonbinary, it has been easier to identify as pagan than Wiccan. They are currently studying Northern Tradition Shamanism in the Northern Tradition Shamanism Guild.
