I dunno. :?:
I can't help thinking some of the people in that video would not have been happy having someone take the piss out of their beliefs. It's a bit like those birthday cards where you have a 1950s photo with a dirty joke as the caption; I bet a lot of the people in those photos would have been horrified at the idea of having their pictures used like that.
Isn't it just evangelists at church services with the music dubbed over the top? If they are actually dancing and aware, their footage was being used like that then great; then again, if they didn't it could be seen as a bit sneaky.
Although I don't share their beliefs, I wouldn't want to hijack the meaning of their worship, I'm sure it means a lot to them.
Of course, it could also be my being a reactionary git.
