A Texas elementary school teacher, who is black, was terminated from her job this week after she was exposed for posting a series of proudly "racist" anti-white comments on social media, Fox News reported.

The teacher, identified as Danielle Allen, 29, who used the alias "Claire Kyle" and declared herself a "black supremacist" in her X-Twitter bio, went on an explicit and bigoted rant after she discovered her sister was dating a white man, who she suggested she would have killed by her own boyfriend.

Despite the use of a pseudonym account on the social media platform, which has since been deleted, it didn't take long before internet sleuths were able to capture all of Allen's racist posts with screenshots and determine her true identity and where she worked -- Thompson Elementary School in the Mesquite Independent School District.

Fired over a "series of alarming, racist statements"

On Tuesday, Mesquite ISD posted a statement that said it "became aware of a series of alarming, racist statements posted to the X (formerly Twitter) account of a teacher at Thompson Elementary. Upon learning of this situation, our Personnel staff began an immediate investigation."

"As of this morning, the employee is no longer a part of the Mesquite ISD organization and is not eligible for rehire. Due to privacy restrictions, Mesquite ISD cannot comment on the details of Personnel matters," the statement continued.

The district added, "Nevertheless, the highly offensive statements posted to her X account do not reflect the values and standards of Mesquite ISD, and the district condemns them in the strongest terms."

Teacher posts racist rant, brags about being unfireable

The saga began when Allen posted a picture of her sister cuddling on the couch with her white boyfriend and expressed outrage over a series of tweets that a "pasty" white "cave dweller" who looked like a "Trump supporter" was in her "NEGRO ONLY house."

She also posted a screenshot of purported text messages with her own boyfriend that asked him to "Come and kill him for me," promised to "help you hide the body" and urged him to "bring all 4 of your guns."

Those posts understandably sparked outrage and further scrutiny of the "Claire Kyle" account, which proudly declared in the bio that she was a "black supremacist," revealed several other racist anti-white screeds as well as that she was an elementary school teacher.

Ironically enough, Fox News reported that as social media users began to uncover Allen's identity, Allen initially bragged in a post, "Y'all have found my job," but added, "They told me to delete the post, but my job is safe since I did not directly wish harm on ALL White people. They laughed and told me to watch what I say, and I'll be good to go."

"Just talked to the school board and my job is safe. I told them it was a joke, and they know I'm not racist so have fun," she wrote in another post, and also posted a video of herself walking through the halls of a school as she said, "Twitter thinks they can take my job away from me. … Call me every name under the sun, but you all will never call me unemployed."

Not as untouchable as she thought

As the statement from Mesquite ISD proved otherwise, however, that simply wasn't true, and CBS News Texas reported that Mesquite ISD Superintendent Angel Rivera issued a subsequent statement to further disabuse Allen of the notion that she had been unfireable.

"Let me be clear — there is no place for racist statements in our community or our schools, and we condemn them in the strongest terms," Rivera said. "To say the statements in the posts do not reflect our district's values and beliefs is an incredible understatement."

"Some posts allege that district and campus leaders were aware and fully supportive of these offensive viewpoints. Not true. Sadly, we live in a time when some are quick to accept outlandish, unsubstantiated claims as facts while destroying reputations with a few keystrokes," the district superintendent added.
