All of those events combined do not equal the massacre and destruction that took place in the Holocaust, so your comparison doesn't stand
Those are examples, food for thought, a whetting of the appetite. Hence why I said "need I continue" at the bottom of my post. There are
dozens more examples of Jewish persecution over the ages.
Now, I'm no historian buff, but I'd wager that over the course of the last 5000 years the number killed is significantly more than 6-7 million people. Additionally, unless you're an historian buff, you don't know the extent to which Jewish people were persecuted, raped, and robbed during the previous calamitous periods. In fact, I'd further wager that the persecution the Jewish people experienced at the hands of the Mitzrim was orders of magnitude more egregious than what was experienced from 1939-1945.
You can't compare those to the holocaust which took millions of jewish lives and is still very fresh on our minds. And while the younger generations may have no issue driving german cars (especially with globalization switching around who actually designs builds and owns these cars) many of us have a grandparent or two who would cringe at the site of their grandchild stepping out of such a car.
Again, aside from the temporal proximity, there is no real distinction to be made. Yes, I'd agree it may be emotionally disturbing to someone who survived the Holocaust to see one of their progeny step out of a German-made vehicle. However, emotion is certainly not infallible, and it certainly is not perpetually (or ever) logical.
Despite what you may have learned, German ≠ Nazi, and German car manufacturers ≠ Nazi.
Besides the fact that most of the companies you mentioned weren't around during nor did they participate in any way in those tragic events, while many of these german companies supported (or were at least visible during)the holocaust one way or the other.
So just being in existence during 1939-1945 is enough for you to boycott? Interesting approach.
i dont think time will change anything with the holocaust, with video and museums
So video is the saving grace? In 100 years, the Holocaust will be but a blip on the world's historical radar. You may not like it (hell, I don't like it), but them are the facts of life and time.
