The most popular white churches are no longer Baptist, Methodist, Presbyterian or even Christian Reformed. White Christians now prefer non-denominational churches that just "teach the Bible." At non-denominational churches charismatic preachers are free from the oppressive traditions of established denominations, such as doctrine developed over the centuries by Biblical scholars.
In addition, "non-denom" or "community" churches are more fun: the theology you are getting from the pulpit could be in the Reformed or Arminian tradition, or maybe something newer and more exciting that your young, dynamic pastor just thought up. Why build the foundation of your church on the likes of Calvin or Arminius when you could base it on the oscillating theology of your hip pastor?
Non-denominational churches are so popular that many churches that actually belong to a denomination will drop the denomination from their name. For example, Springfield Christian Reformed Church becomes Springfield Church (with "a Christian Reformed Ministry" in tiny letters underneath). Or maybe, Riverside Church if it happens to be next to a river. This is a great tactic for tricking white Christians into thinking that they are visiting a non-denominational church.
