It is also 100% effective in losing your ability to think critically (see the TED talk about "filter bubbles").
I try to read authors that I disagree with but respect. A certain amount of bias filtering is inevitable, but I like to think that I at least try to listen to opposing viewpoints. Especially about issues that matter.
When dealing with issues that don't matter, like Apple fanboys, I find it easier just to ignore them.
My solution is not to read authors that I dislike. I find that it is 100% effective.
