First, part of my claim is that you absolutely can find examples where CNN puts Harris or Biden in a bad light. To properly debunk me you would need an analysis of how frequently they show either party candidate in a good vs. bad light.

Second, and more importantly, you're trying to debunk what I clearly stated as my experience of viewing CNN. I didn't claim it to be a universal truth, only a pattern I have noticed when I have taken the time to browse CNN's site.

Debunking is useful when someone is proposing an argument as a scientific, or logically based, argument. Its pretty useless when the statement is only based on personal, anecdotal experience.
