That's right. Germans abroad such as myself do appreciate that a lot. :)
It feels like once again some Unix philosophy could be applied for the better: be strict in what you emit (ie. be kind and consider how your behavior reflects on you, but also be cognizant of your or your culture's history), but lenient in what you accept (ie. do not take offense easily/unnecessarily).
This is a ridiculous comparison. A proper analogy would be someone with a swastika symbol on their shirt talking to a Jewish person. I think we can all agree that wouldn't go well.
You have absolutely no idea what you're talking about. Old people here (80 and up) still loathe the Germans and for what was done during the war. Their personal involvement is what make it impossible for them to move on. But as one of their children I have absolutely no grudge against Germans, old or young, simply because I wasn't personally involved.
Jewish people come in all shapes and sizes, and I know quite a few of them. The bulk are very well educated and are able to see history and their own part in it quite clearly. They are definitely not going to like some one with a swastika symbol on their shirt but the chances of that happening here in Europe are relatively slim because there would be a lot of other people - non Jews too - who would take offense.
That's nothing to do with personal involvement but with recognizing that those that wish to engender a second round of Nazism in Europe need to be dealt with before they become a problem.
The swastika has existed for thousands of years before the Nazi party ever existed and has never represented war before Hitler borrowed it. You can still see occasional swastika designs all around Europe in pre-WW2 buildings as well as used commonly outside of Europe and North America.
The question of the usage of the swastika then becomes intent. eg is it used as part of a Pagan, Indian or other non-Nazi design?
Not really. You wanted a more direct comparison with the GP and the GP wasn't wearing his T-Shirt in support of the Nazis. Which means either your counter-analogy is also flawed or the context should be that the wearer isn't doing so in support of the Nazis.
Their death directly lead to the other events which lead to other events. You can always blame the fate if death was natural, but if some other party was involved, that party directly played god with their actions and ruined someone else's life trajectory and thus their descendants life trajectory. And now you find out that the descendants of the murderers are proud of their heritage and hero worship at the expanse of you.
I won't comment on where exactly the line is, but this is on the level of me getting angry over someone practicing horse archery because of the Mongol invasion.
Horse Archery was a common martial technique which predicates the mongols (Its way ancient), and during the mongol period it was practiced by a lot of civs, both allies and enemies of the mongols.
But yes, a lot of people still hold a grudge against the Mongols in Asia and Europe
