A black teacher has been sacked over sick social media posts where she told how she had asked someone to kill her sister’s white boyfriend.

Danielle Allen, 29, used a fake ID on Twitter to hide her real identity and, report local media, boasted about her hatred for white people.

Using the alias ‘Claire Kyle’ Allen – from Mesquite, in the US State of Texas – penned a series of hateful tweets pouring out her poisonous views.

‘Claire’ boasted of how she had asked her boyfriend to kill a white man her sister was dating after trying to break them up.

She continued the rant declaring that her home was “negro only”.

In another post, Allen as ‘Claire’ told how she enjoyed “being racist” and would “never change”.

Allen was only stopped when a user on the social platform X, formerly Twitter, tracked down that she worked at Thompson Elementary School and tagged her bosses on one of her vile tweets.

Mesquite schools superintendent Angel Rivera said Allen was forced to resign and will never be able to come back as a teacher.

He said: “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.”

Allen has so far not commented on the matter.

She deleted her tweets but many are still available on social media as screenshots.

One tells someone who commented that many white people are good: “A white man???? A good dude??? You smoking crack??”

And in one ironic tweet she boasted about how despite her views, she could never be sacked.

She said: “Call me every name under the sun but y’all never be able to call me unemployed.”
