The comments came at a Jan. 31 fundraiser for Oregon Republican Senate candidate Dr. Monica Wehby. A video of the speech, uploaded to YouTube, shows Carson discussing how the "secular progressive movement" wants to "fundamentally change who we are." The majority of Americans who have "common sense," meanwhile, are "afraid to speak out," Carson said, because "they will be targeted, they will be called names, they will be investigated by the IRS, and all kinds of unimaginable things will happen."
A few moments later, Carson brought up the Nazis.
"There comes a time when people with values simply have to stand up," he said. "Think about Nazi Germany. Most of those people did not believe in what Hitler was doing. But did they speak up? Did they stand up for what they believe in? They did not, and you saw what happened."
"And if you believe that same thing can't happen again, you're very wrong," Carson then added. "But we're not going to let it happen."
