A feminist has quit Twitter after provoking rage by claiming she was "not sad" to hear about a young boy killed by an alligator because he was white.

The heartless anonymous firebrand was one of many vile tweeters who published shockingly racist diatribes about tragic two-year-old Lane Graves, who died after being snatched during a family holiday in Florida.

The cowardly social media star writes under the pseudonym Brienne of Snarth and boasts more than 12,000 followers on Twitter.

But there are now calls for her true identity to be exposed. It has also been suggested she has been sacked from her day job, although these claims cannot be confirmed.

She wrote: "I'm so finished with white men's entitlement lately that I'm not sad about a 2 year old being eaten by a gator because his daddy ignored signs."

It is believed that Snarth is white herself, although she uses a silhouette as her Twitter profile picture so it is impossible to tell for sure.

After her shocking comments went viral, supporters came out to back up the shamed social media star using the hashtag #WokeGatorTweet.

The word "woke" is often used by people who consider themselves to have awakened to the reality of the oppression of women, black people and a range of minority groups.

Dozens of other people also published tasteless tweets about the tragedy which focused on Lane's ethnic background. Most of these vile comments are too sick to publish.

Some Twitterers compared the public outpouring of emotion Lane's death to the outcry which happened when a young boy fell into a gorilla enclosure, forcing zoo keepers to shoot the animal.
