This is where Critical Thinking is important, analyze what you read and look for opposing viewpoints. If you can't find opposing viewpoints and you agree with what your reading then you are drinking Kool-Aid at the neighbourhood cult meeting.
Critical Thinking is not just being critical about what information you absorb, it is also being critical about where your own ideas and "truths" come from.
Take this blog, it is one point of view, what if you find two or even three other points of view? Don't shy away from them, check them out see how they fit together. Sometimes two opposing points of view is really just two different perspectives of the same idea.
