Portraying one side as having justification for their acts and the other as acting without reason.
Systematically quoting without confirmation the justifications given by one side, not the other.
The Propaganda technique called “framing” is, quite self-explanatorily, framing (a.k.a. decorating) what is being reported about one side’s actions in one way and what is being reported about the other side differently - the core content which are the events are described the same but only one side’s views on the why for those event are reported.
It’s a far more subtle technique than outright telling the readers “these are the good guys” or using nicer words for the same actions if executed by one side than for the same kind of action when executed by the other side (mind you, at least 3 of these 4 examples will also use this latter technique, which is about “portraying” rather than “framing”)
My contribution frames both sides equally thus both actors seem equally rational in their actions and the justifications for their actions given by both are there with equal prominence. It gives both sides’ justifications to the readers and leaves it to the readers to decide who to believe and which justifications they found valid. That’s how actual Journalism aims to report: giving what they have to the readers and leaving it up to the readers to decide who to believe.
