This really is pathetic. Play Death Metal, and the guy comes off seeming unholy. Gee, really? I don't like these faith-healer types any more than the next Catholic, but come on, people!

He's not swatting anyone. Look closely; his jacket doesn't contact the people (most of the time). They are being "slain in the Spirit" (supposedly), a five-century-old religious phenomenon, older than premillenialism, dispensationalism, and most other Protestant "isms." He waves at them, and they fall down. It's the frantic editing and the death metal that makes it seem violent.
Rather, it's the theatrical use of a coat which allows him to "slay" more victims simultaneously and achieve a greater effect.
That's show business.
