This didn't happen at our convention. But there were many up beat videos shown on the monitors, which get the crowd a little bouncier and happier. so I dont think the majority have a problem since it's seems to be the direction the society is going and it feels good to the average r/f.
At one point, my husband said, they are loosening up. I jokingly replied, I know, we even have a choir (that's exactly how they looked on the big screen) now. He gave a quick laugh, then said, that's not a choir. I said, I know, I'm just kidding.
Edited to add a picture similar to some of the video they showed at the convention but I got a couple of side eyes when I jokingly said we now have a choir, lol
