It’s not a dishonor to their memories, or the atrocities committed, to call that out. It is not a dishonor to say there are stark and real similarities between the way the US is operating and treating civilians.
I personally find the opposite, IMHO it is dishonors their memories to refuse to acknowledge the similarities.
I’ve posted a comment similar to this one here before, and like how I ended it. I strongly encourage you to read about the history of Nazi Germany and how it came to happen. It wasn’t just a zero to death camps, it was 15 years in the making. That history is deeply shocking, as it is depressing, because the parallels and timelines are too similar for anything besides outright discomfort, sadness, and fear between it and the US. But without knowing it, we are ever more likely to repeat it.
One final thing to note: the US has a history of extreme violence, slave patrols and the treatment of non-whites of the 19th century were an inspiration for Hitler.
