Kyle Kashuv, a survivor of the Marjory Stoneman Douglas High School shooting, reportedly went on a racist bender in the months leading up to the 2018 massacre, spewing the n-word in text and Skype message shared with classmates.

He has since apologized, but apparently that’s not enough for Harvard.

Kashuv, an outspoken pro-guns activist who once met with President Trump at the White House, said Monday the university pulled his acceptance after it became aware of the “egregious and callous comments” he made two years ago.

“After careful consideration the committee voted to rescind your admission to Harvard College,” William R. Fitzsimmons, dean of admissions, wrote. “We are sorry about the circumstances that have led us to withdraw your admission, and we wish you success in your future academic endeavors and beyond.”

Even before Harvard dropped him from this year’s class, Kashuv says the reaction to his comments “sent me into one of the darkest spirals of my life.”

Here’s his explanation on Twitter TWTR, -4.83% (click for the full thread):

As you can see, Kashuv, who took a gap year before his intentions to attend Harvard, emailed the dean, asking for a meeting to “make my case face to face and work towards any possible path of reconciliation.” That request was rejected.

“Harvard deciding that someone can’t grow, especially after a life-altering event like the shooting, is deeply concerning,” Kashuv wrote. “If any institution should understand growth, it’s Harvard, which is looked to as the pinnacle of higher education despite its checkered past.”

Kashuv’s thread immediately went viral, and reactions were mixed.
