Religion is entertainment in many ways. Think of all the fundraisers, the potlucks, the group circles, the ladies' and mens' nights, the Alleluia parties, etc., and so on. That is just for one part of the Christian Church.
While I am a Christian, I disagree that football isn't religion. You've never probably played, watched, been part of, gambled, or lost on a team. It is as emotional, or more emotional than most anything that happens at church.
Think, too, of how football supports certain people's lives, just as does the church. Both have their superstars. Pele and Beckham are probably names that even non-footballers would know, similar to non-Christians having heard of Jesus.
I know people who live, eat, breathe football. I know people who live, eat, breathe religion. The corollary is that each sport is a different religion to whom devoted believers are obeisant, and that every religion is a different sport.
First, we have to kick down the divide of conceptual propaganda from the heads of large organisations and the church, then we can talk. Till then, we will be trading swats and that is it.
