I think much of the traditional news reporting isn't necessarily against Bitcoin, but more likely doesn't want to challenge their audience or the status quo too much. Alternatively, when the price is high or low you will find some talking head who is wishing for it to be the other way. If you search there are some good media sources who present unbiased reporting, but much of what people refer to as mainstream media is little more than "light entertainment" in my view.

The easiest answer is to select different news sources, seek out sources that present both sides of the "coin" when necessary.
