Hello!
I agree with professor Tilley, that doing something with an intention to make somebody angry is just plain wrong.
At the same time I believe it's ultimately our responsibility if we get angry or not - it isn't easy, taking responsibility for that, but it can be done!
I'm living in Poland, but I can't say I've met a holocaust survivor. I probably did, but didn't have a chance to talk or listen to him or her. I have also never been to Auschwitz. A much smaller concentration camp was situated like 100 meters from where the family of my Grandfather lived - they were just everywhere... My grandfather was a slave labourer for five long years and told me about it so many times, we even wrote a small book about it. I've also had an opportunity to talk with German veterans of WWII - one of them was drafted into the Luftwaffe at the age of 16. The other one served on the eastern front in an anti-armor SS unit.
They all had a nice and good life in comparison to the concentration camp victims, from what I've seen and read it was a horror beyond any imagination. In Polish schools they make sure that this point comes through.
But I also have another experience - in Poland, before 1989, we were under Soviet influence. The government tried to control most aspects of people's lives - and while it tried to promote model building as means to expand the skill and knowledge of the youth, building anything German or American was strongly discouraged. If you had a model of something German it could get vandalized by "unknown offenders" the minute you turned away. It was so good to have it change in 1989, but I'm still allergic when somebody tells me what to model and what not.
I believe a part of the problem here is the understanding for our hobby. If you put a swastika on a toy, it's offensive. If yo uput it on a museum quality historically accurate miniature it's something different. Sadly, most people see our models as "plastic toys".
Well, that's a bit longer than I intended it to - thanks a lot if you read this far and have a nice day
