I don't think I'd call myself high on the emotional intelligence skill, but it's that restraint I pride myself on. If that's emotional intelligence, so be it. I think I recognize the emotional spin, and resist. If I have any emotion, it's anger.
In churches, they employ some propaganda in the "positive" sense, I guess. Catholics (and Orthodox) pride themselves on being a religion "for the senses". The imagery, the adornment, the incense, the rituals, etc.. It creates a sense of mystery. These visual and auditory techniques are propaganda, in a way. I think it has capacity for harmfulness, but not necessarily.
I see Pentecostal churches employ similar techniques, but in more harmful ways. Their music is full of repetitive mantras... a whole 30 mins or an hour of this music puts a lot of people in a trance. The crowd is under their control. Mass hypnosis even. Half of the time, the preachers have already deluded them that they're miracle workers or have supernatural powers. They can push these people down and put them in a stupor. The problem really lies in the authority structure in these churches - instead of a presbytery or group, it's ruled by cult of personality. One preacher. That means most of the tithes go to one guy. And many of them live extravagantly on it.
