The equivalency argument is used when one entity is off-the-charts biased while another might simply cater to an audience but still strives for a measure of respectability. Then when it is noted how ridiculous the one side has become, it is argued that they all do it. I'm sure anyone can argue that it depends on perspective, but from my perspective, the Tribune is off-the-charts biased against BYU, and there isn't really a fair equivalent.
