Many are in response to state governors and other politicians saying they won't accept refugees.
That comparison has some strengths but also some weaknesses.
It's true the U.S. was strict in admitting refugees from Germany and Austria before the Holocaust. The country stuck by its quota system, on the back of popular opposition to Jewish refugees. (Video via United States Holocaust Memorial Museum, National Geographic)
Radio personality Martin Goldsmith explained, "There was a certain strain of anti-Semitism in this country in 1938. ... Fifty-three percent of the American people who responded to this poll declared that 'Jews were not like the rest of us.'"
That's remarkably similar to a recent Public Religion Research Institute poll, which found 56 percent of Americans say Islam is "at odds" with American values.
But there are important differences. People against admitting Syrian refugees today mainly cite security concerns.
"I will not roll the dice and take the risk on allowing a few refugees simply to expose Texans to that danger," Texas Gov. Greg Abbott told the press.

The country was in the midst of the Great Depression at the time, and Americans worried refugees would compete for jobs and burden social welfare — hence the quotas. (Video via History Channel, National Archives and Records Administration)
Still, the movement of Syrian refugees in Europe is the biggest since the second World War, so the comparisons aren't surprising. (Video via CNN)
