Let’s see here. In America, Naziism and Communism denied the most basic human rights and were evil and were to be opposed. Yet you did not mention Jim Crow here in the USA. Jim Crow denied the most basic of human rights. Therefore did you neglect to say that the Americans in charge of the nation were just as evil as the communist and the nazis?! Or am I missing something in the wordings?! Maybe, the nation just was not ready to extend its boundaries to all of its citizens yet. Not enough economy for every one to be included?
“Therefore did you neglect to say that the Americans in charge of the nation were just as evil as the communist and the nazis?!”
One has to be cognizant of the realities of the times.
When the constitution of the US was written and for a long time thereafter “We the people” did not include blacks, therefore they weren’t supposed to have any rights to began with, so “we the people” didn’t believe “we” were denying them rights, any more than we today think that we’re denying mules the right to run free or to vote.
Applying moralities or definitions of today retroactively to dead people of a totally different era is a useless exercise in virtue signaling and revisionism.
Who knows maybe if the animal right activists of the future get their way, they will castigate us tomorrow for chaining, caging, slaughtering and eating animals today.
Anyway to answer your question, no the nation leaders during the slave era were not “evil” like the Nazis and communists if you judge each by the prevailing morality of their respective times and places.
It’s also important to point out that two cultures that are anathema to each other can both existat the same time provided they do not interact and do not come into close contact with each other. So even though Nazism and Americanism are anathema, Germany and the US could have both existed if each minded their own business.
Frictions from different values and moralities only arise when two cultures come in close contact, as for example is happening today between the West and Islam.
