This is a direct consequence of "the war on terror" attempting to redefine the military strategy of asymmetrical warfare as terrorism and inherently immoral.

To sell the bullshit "war on terror" the easiest way to make the US seem righteous was to degrade the public's sense of why people violently resist and reduce it to the act of violently resisting an organized traditional military is immoral unless the thing resisting is also a traditional organized military.

I am glad that narrative is breaking down though as the distortion of how and why violent conflicts occur is dangerously blinding to a basic understanding of the world.
