Blind trust in anything is naive and dangerous. Likewise if we choose to trust only those who agree with us we stand to learn nothing. And further, it's impossible to function without trusting some people and institutions, in some ways, some of the time.
I would trust, CNN, for example, to report about some topics but not others. There are some neat tools to help you do this. (which you also have to think about trusting) Have you looked at ground news?
