Neil deGrasse Tyson has been a rock star for the left for many reasons. He's a favorite scientist, with his record as an astrophysicist, author and scientist.

But he's had to apologize now for a Twitter messate that was, in fact, correct.

Maybe that's why the left objected.

Here it is:

TRENDING: Man arrested for alleged brutal attack on 77-year-old veteran wearing a MAGA hat

In the past 48hrs, the USA horrifically lost 34 people to mass shootings. On average, across any 48hrs, we also lose… 500 to Medical errors

300 to the Flu

250 to Suicide

200 to Car Accidents

40 to Homicide via Handgun Often our emotions respond more to spectacle than to data. — Neil deGrasse Tyson (@neiltyson) August 4, 2019

In it, he pointed out that as catastrophic as mass shootings are, with the 34 people lost over the weekend, during about the same time about 500 died due to medical errors, 300 because of the flu, 250 because of suicide and another 200 to car accidents.

AP commented: "Neil deGrasse Tyson has learned after a tweet that pointing out truths is not always helpful. The astrophysicist and author apologized Monday for a Sunday tweet in which he noted more people died in less attention-getting ways in the same two-day period as a pair of mass shootings."

Tyson had noted, "Often our emotions respond more to spectacle than to data."

It prompted outrage on the left.

Criticisms on his statement ranged from the fairly mild disagreement to obscene allegations.

"One can be factually right, and still be wrong," wrote one.

Another Twitter user wrote: "The facts you use can be technically correct, but if you apply them in the wrong context or compare them to things that aren't equivalent, you can still be wrong."

Tyson explained on Twitter he miscalculated how his comments would be received. He said he had hoped it would be helpful.

Tyson, who has hosted TV series including "Nova," also has released "Astrophysics for People in a Hurry."

Talk-radio host Rush Limbaugh noted how quickly liberals "turned on one of their favorite scientists."

"He told 'em this [shooting] isn't a big deal. This is an emotional reaction. These shootings are not that frequent. And, man, are they hating on this guy."

One anti-gun activist, Shannon Watts, said: "Cold take, Neil. 200+ Americans died from gun violence in the past 48 hours. And you list causes of death that are researched, regulation and also happen in other high income countries ... ."

Far-left activist Marc Lamont Hill said, "This is dumb."

Tyson said: "My intent was to offer objectively true information that might help shape conversations and reactions to preventable ways we die. Where I miscalculated was that I genuinely believed the Tweet would be helpful to anyone trying to save lives in America."

He said he learned his information can be "true but unhelpful."
