I'll assume it's the former.
The reason why I'll assume it's the former is because we should always assume good faith - it's even a posting guideline on HN[0].
Also we are talking about a swatsika beeing used with near certainty in a western context. Maybe my reaction was indeed a little too “alergic” — I grew up in Austria and I have memories of Nazi grandfathers giving their neonazi ancestors all those nazi insignia. People who after the 10th beer start praising Hitler and demand new genozides, once they are in power again.
Given my background seeing somebody claiming their swatsika is not linked to nazis because it faces the wrong way is just something that doesn’t fly — I have heared that (and similar) excuses far too often from people who were definitly convinced nazis.
Btw. I don’t know if that guy is a nazi or someone who wants to provoke, but he certainly seems to know about the difference between right and left facing swatsika and thus could’ve anticipated the whole discussion.
