As intriguing due to the fact the excerpt states ''<span>To them he was just one of the "attractions” at the Party.''</span>
<span>The
political unrest and economic instability of the 1920s and the 1970s
provided an opportunity for extreme political parties to blame
more-moderate political parties or the ruling government for either not
doing enough to solve the country’s issues or for causing the problems
in the first place. In both 1920s Germany and 1970s Cambodia, these

Whittier used "We" and "Thou" as forms of repetition in his song of slaves in the desert.
We: He used we as to show that basically slaves WERE NOT alone in this at all. In a way at that time, every single slave was connected with each other no matter what.
Thou: From what i have seen, Whittier is using "Thou" to refer to God. For example: "We are fools, but Thou art wise"
For the devices, he's using Anaphora for "Thou" and maybe Conduplicatio for "We".
I think its a predicate hope it helps
