(Sorry, lemmy is having a moment)
"We should be more tolerant of dogwhistles" is a new one for me, damn. No, in this case "the Nazis even broke their own laws" was the point - which was false, and is in line with sentiments expressed in other common nazi propaganda.
We risk nothing by calling out and rejecting it. It doesn't devalue resistance movements, there was no resistance movement mentioned, just some vague officer (who might even be real!) who was investigating something and was presented as a counterpoint to the lawlessness of the Nazis.
I'm not sure why we're discussing sensitivity to dogwhistles? If I mentioned them, which I don't see that Ive done, it was by accident - nothing here has been a dogwhistle. This is just plain misinformation, and as I've repeatedly said, I do not think it was done intentionally (so the poster's previous behavior wouldn't be an indication).
