I wasn't going to comment on this because I'm totally floored by the amount of negative attention this obvious attempt as humor has gotten, but to not "give them the time of day" means you would rather ignore them.
To use the old cliche: "Those Who Ignore The Past Are Doomed To Repeat It."
Maybe it was in bad taste (I thought it was funny, but I'm entitled to that opinion), but if somebody were to watch that, a child perhaps, and didn't know about Hitler and the German history, it gave parents a perfect opportunity to teach their kids about it.
There was nothing in that video glorifying Hitler or Nazis, so why, again, is everybody so pissed?
