Thats the thing. Back when it was written, the idea waa that the only way to wake up the “sheeple” was to insert the “uncomfortable truths” in art.

The problem is that this is idealism. The white French man was materially happy ignoring French State crimes in the 3rd world. A more effective way of doing politics is to enlist the help of the oppressed, such as women and non whites. Ofc the white man was also oppressed by capitalism, but the avg liberal could live with it.

So in short, agit prop is good, but material, down to earth politics is better.
