If I might make a suggestion, you could think about a longer version which incorporates the other Democides of the 20th century. Armenia, the Ukraine, China, Germany, and Cambodia could be included.
A reference to Professor Rummel might be in order as well.
Or you could do a series focusing on each case in turn. Let me know if I can be of any help.
Of the video or the essay? On the video, we deliberately kept it to a max of 5 minutes. We’re trying to catch the attention of non-readers....which is most Americans today, sadly. Folks who won’t spend ten minutes reading also won’t spend ten minutes watching a “hard” video, (as opposed to infotainment mind candy on TV.)
