Everyone isn’t guilty to the same degree. Seeing guilt at different degrees doesn’t necessitate innocence. Casting blame evenly or vaguely isn’t good.
There are many instances of guilty vs less guilty throughout history. The current world is built off of the colonizing of the Americas and the lessons and reactions from that. There’s no both sides to that. The west was and has always been wrong with imperialism. Kissinger doesn’t need to be white washed.
