As for the kids, go back and watch the vid again. It shows what looks to be pre teens boxing. I mean they are wearing headgear but they are wailing on each other. Then it shows one of the kids crying. I don't know. It just didn't sit well with me.
I haven't watched it, but certainly nothing wrong with being bothered by children crying, DA. I don't say that as a judgement of Fight Church, but certainly those images affect everyone differently.
