The idea that propaganda cannot be propaganda if it is delivered in a dry, objective tone is nonsensical.
The Israel/Palestine conflict is a great example of this - especially in the US. Anyone who has closely watched the mainstream news media cover the situation in Gaza, or the college protests that sprung up as a result, has witnessed consent for Israel’s war being manufactured in front of their very eyes, along with the vilification of anyone who stands opposed to it. The fact that it is delivered by seemingly professional journalists in a somber, even tone has no bearing whatsoever on how accurately it describes reality.
