Did I say liberals and conservatives share equal bias? Please don't misrepresent what I'm saying. Also, please take a good look at yourself and your motives before accusing others of self-delusion.
Well, if you don't want me to misrepresent what you are saying, don't misrepresent what you are saying:
"Liberals can look at Fox News and clearly see conservative media bias...yet, are totally blind when it comes to liberal media bias. I've never understood this."
This is a claim of total blindness. Thus, unless conservatives are not totally blind, liberals are even more blind than conservatives. I gave you the benefit of the doubt and assumed you meant that liberals and conservatives are equally totally blind. If you want to claim that conservatives aren't totally blind and are less biased then liberals, fine. This would still imply by your theory that liberals are more adapt at detecting conservative bias that conservatives are at detecting liberal bias:
"I have a theory...one's ability to detect opposing ideological media bias is directly proportional to the degree of one's own ideological bias."
Then again, you probably didn't say what you really meant because what I think you really mean is that ideologues don't detect better, but imagine they detect better, opposing bias.
