More can be written, but you might like to start with 'Did TIME magazine suffer a backlash for naming Hitler "man of the year"?' by /u/LoadofBees , /u/intangible-tangerine , and /u/restricteddata .

For a summary of that issue's coverage of Hitler, you can see "What were American attitudes towards Nazi Germany pre-World War 2, and vice-versa?" by Prufrock451.

This is not to discourage discussion. More questions, data, and debate are welcome.
