It's been my understanding that these days, the term Nazi is used to describe just about any hate group, whether they have anything in common with the "originals" in Germany or not, as long as they are a hate group targeting a certain type of people. I didn't understand what was offending about the comment that got AQH banned, but I do understand enough about what happened between the wars in Germany to see some similarities between what happened then and what is happening today. While I'm not quite sure I understand completely what lead to the rise of Trump, I understand the basics of what happened in Germany after the war. All the blame was placed on them, which hurt the economy there more than anywhere else, and the people bought what Hitler was selling as a way to fix things.
The phrase, which I hesitate and even fear to quote, was on the signage over nearly all the Nazi concentration camps. Of course, "concentration camp" was really a euphemism for "death camps".
For anyone who was involved in WW II or who had friends or relatives who were involved or put to death in the period where the Nazis were in control of Germany and the conquered nations, that phrase represents the most pure evil.
In the last century, such evil was only equaled by the Khmer Rouge which killed about a quarter of the population of the nation it lead for just half a decade. In the case of Cambodia, they essentially killed the business, professional and legal class, eliminating also small business people, teachers who were not Socialist / Communist in their attitudes and opposition in general.
Comparing the Nazis or the Khmer Rouge with today's bi-partisan political antagonism in the US is disrespectful to the millions who died under the totalitarian regimes that systematically assassinated whole segments of the population.
There is absolutely no comparison between an outspoken politician in today's US and the National Socialists in Germany or the Socialists in Cambodia in the last century. It's really disingenuous to even try to compare them.
