I think you’re negative votes speak for themselves, but this is pretty obviously showing that there is Media bias.
I mean obviously it’s nearly impossible to prove that the media is not biased, what would a test for that even be? But showing where similar events get wildly different coverage does lead towards evidence that the media is biased.
Now, of course, the media can’t cover literally everything equally all the time. But let’s be honest, we know where the military lies, we know what the government is saying in official speeches, and we know what the media is pointing to. When everything lines up, it’s pretty fucking obvious.
