They did not ask whether Hitler's regime was good, they asked whether "it had a good side".
It had plenty of good sides - otherwise he would not have been elected democratically in a country with highest educational level.
It is just not politically correct (in US at least) to admit anything but bad about any negative figure/event in history. That is why instead of analyzing why such atrocities came to be, people just think it was an abberation of a "crasy maniac" or such crap and boldly go forward towards the next one...
There are plenty of Hitler-admiring people in Russia, of all places! What do you think of that?
