The same way a Roman instrument of torture has been the crucifix idol of modern Christianity despite your Gods admonitions against such things.
Or do I need to pull up some of Fred Phelps ramblings to show there are nut cases in every religion?
Interesting that they would choose the Rune Othala as it has not only the implication of "Roots" or "Beginnings" to it, but it can also mean "retreat" or "withdraw to whence you came".
There is an important distinction here. In ancient paganism, the idols WERE a people's gods. In Christianity, a crucifix is a symbol of Christ's death on the cross. That's ancient Christianity, not modern, since most "modern" strands of Christianity have criticized the use of a corpus on the cross, since they like the emphasize the Resurrection.
