This is tossed in as if to imply that shutting down the radio station would have saved lives and that the US was therefore complicit in those deaths.
I am never swayed by arguments like this. A culture that produces that kind of hatred will not be stopped by losing a channel to express it. Word of mouth spreads quickly, and actions speak even louder.
Not to mention, per the sidebar, the radio hosts were already disguising their meaning in places despite not experiencing a threat of censorship. "Talking in code" for something that has already become socially acceptable, has its own social purposes - it allows for the hateful to bond over their hatred more strongly than if they were explicit, because the "shared language" is a strong signal of in-group belonging.
