... Evangelicals regard Aikido as an "eastern religion." .
I've always found it amusing that many Christians think of Buddhism, Islam, Hinduism and so on as "foreign" religions. Didn't Christianity start off in Asia?
For whatever reasons, the Romans and their successors imposed the "foreign" religion of Christianity over all of the indigenous "native" religions in Europe.
I gather that in Greece there is a group trying to revive the pagan religion of Ancient Greek times, and the Orthodox Church there is doing its best to suppress this.
