GQ magazine is under fire for an article entitled "F*** Ben Carson" in which the writer slammed the GOP presidential candidate's recent comments on the Oregon college shooting. 

The author, Drew Magary, argued that the Republican campaign is an "arms race of stupid" in which Carson is trying to stand out from the competition by making "even sillier comments."

Meantime, Carson is coming under a new round of criticism for suggesting the Holocaust could have been avoided if Jews were armed.

“I think the likelihood of Hitler being able to accomplish his goals would have been greatly diminished if the people had been armed,” Carson said on CNN. 

In an interview on "The Kelly File," Carson's campaign manager Barry Bennett said the former neurosurgeon was "sickened" by the GQ article.

He noted that a University of Pennsylvania professor called Dr. Carson a "coon" on Twitter this week.

Bennett said when he called the school to complain, they told him that the professor, Anthea Butler, was practicing "academic freedom."

On "America's Newsroom" this morning, Tucker Carlson said Carson's point about the Holocaust was not "insane," but the remark seems unhelpful for his campaign overall. 

"You have an entire universe of things you could talk about, but you have to narrow it down to just a few in order to get those points across. People can't hear you if you don't have a clear and consistent message," he said.

The Anti-Defamation League called Carson's statement "historically inaccurate", adding that, "The small number of personal firearms available to Germany’s Jews in 1938 could in no way have stopped the totalitarian power of the Nazi German state."

Carlson said it's a theoretical, academic question that could be worth debating, but neither side knows what would have happened.

He added that when someone mentions the Holocaust, the issue gets "muddied up by emotion."
