Only sticking point is the use of “demonic”.

It’s a silly term based on fairy tales and is needlessly dehumanizing rhetoric that not only makes the piece feel childish but also opens up the piece to criticisms that will distract the audience from the point that is trying to be made.

Why not just use “Imperialist Captors” and actually sell the anti-imperialism angle? That seems like it would be much more effective at getting the point across without sounding, IMO, childish.
