The drama, Ode on a Burial Mound, is one of 17 original scripts of the Order, Santee Lodge 116.
“This is our O-A Week Indian Pageant. We have one every year. We bring in a pageant director, sometimes it’s a member of the lodge and they’ll write it and direct it and it all comes together. We don’t know how, it just does,” CJ McIllrath, a Myrtle Beach Eagle Scout, said.
In general, whites shouldn't be playing Indians. But since this is a private, amateur performance rather than a public, professional one, it doesn't take jobs from Native actors or spread misinformation widely. Therefore, it's not a big problem.
Of course, the Order of the Arrow has offended Indians in the past by using Plains stereotypes in its ceremonies and performances. I don't know whether it's still engaging in this behavior.
