The topic was broached and reported on in a profile of Carson in The Washington Post.
"You can't dance around it," Carson told The Washington Post's Ben Terris. "If people look at what I said and were not political about it, they'd have to agree. Most people in Germany didn't agree with what Hitler was doing…Exactly the same thing can happen in this country if we are not willing to stand up for what we believe in."
In February Carson suggested that liberals could turn the country into Nazi Germany.
"There comes a time when people with values simply have to stand up," he said according to The Huffington Post. "Think about Nazi Germany. Most of those people did not believe in what Hitler was doing. But what did they speak up? Did they stand up for what they believe in/ They did not, and you saw what happened."
A month later, Carson went there again, saying that American society today is very similar to Nazi Germany.
"I mean, [our society is] very much like Nazi Germany," the retired neurosurgeon said in an interview with Breitbart News. "And I know you're not supposed to say 'Nazi Germany,' but I don't care about political correctness. You know, you had a government using its tools to intimidate the population. We now live in a society where people are afraid to say what they actually believe."
He went on to list the "PC police" politicians and news that, together, "stifle people's conversation."
"The reason that is so horrible is because the only way that you have harmon and reach consensus is by talking. But if, in fact, people are afraid to talk, you never reach consensus," Carson said. "And instead you grow further and further apart. And that's exactly what's happening, creating a horrible schism that will destroy our nation if we don't fix it."
