Getting a "Final Notification" from any one of the "Christian" websites I happen to belong to, tells me nothing, except that they seek to coerce me into accepting their terms.
Getting 'final notification' notices is now so common-place, that I ignore the term all-together. It's emotionally coercive. Some of the sites that use this terminology are considered "Christian." Sadly, that means nothing. Coercive commercial techniques aren't considered anti-Christian by these entities. Maybe I shouldn't be surprised. But as a Christian, in my naivete, maybe I should be. I thought being Christian should illustrate something better.
