What gets me is that the topic question is asked in passive voice. The natural comeback question to the question is "considered by whom?".
Non-Christians and non-practicing nominal Christians will have a far different criteria for judging what is or isn't Christian than Christians would have.
One aspect of the Christian religion is a set of behavioral codes and morals. Any station whose content touches upon some of those moral codes could be considered "Christian" by non-Christians who don't realize that though those moral codes are part of Christian theology, they are not exclusive or unique to the Christian faith. When a non-Christian hears someone on a talk show mention any sort of codes for moral behavior, they often think it is Christian morals being taught. The truth is, those same moral codes are found in most other religions, and even in secular moral codes that have nothing to do with religion at all.
In listening to 104.7's hosts, I've heard very little mention of anything that could be construed as exclusively or uniquely Christian. Advocating being honest, rewarding hard work, and other such "moral" behavior is not being "Christian". Many atheists also believe that being honest is good, and that hard work should be rewarded, and that peoples' rights should be respected.
