That may be true, but just because lots of people are stupid doesn't mean you can ignore them.
I do not have to listen to people whose views I find intellectually dissonant
As much as we'd like to live in an ideal world, we have to live in the real world, and in the real world, the emotional reaction to Hitler is a very real thing that can't be ignored.
I know that, but the fact that one tries shows one's intellectual superiority and immunity to the herd instinct.
For all I care the Germany in the game can have concentration camps as a unique wonder, but it ain't gonna happen because no vendor would sell the game. Same goes for Hitler as leader.
Most people have done worse things than that. Some people do many things without thinking about money, most things in fact. The fact that Firaxis does think about monetary concerns is no excuse for you to do the same. Doing so puts you on the same moral plane as them. One should not even mention such things.
Wishing that everyone was logical is as unrealistic as making decisions based on emotion.
