Katie McHugh, a Breitbart reporter, demonstrated exactly why her publication has been branded as “racist,” “fascist” and “hate site” in the past by people, after she posted an anti-Muslim remark on Twitter, in the aftermath of the terrorist attack in London on Saturday.

While the rest of the world offered condolences and prayers for the families of the victims, McHugh took to Twitter to blame the attack on Muslims living in the U.K.

Reacting to McHugh's remark, Pej Vahdat, an Iranian-American actor, called her a “moron”. McHugh, however, was quick enough to lash back at her critic by incorrectly mistaking his as an “Indian,” which she posed as an insult.

Other Breitbart employees have been reportedly appalled by McHugh’s behavior on social media, said a report.

"It's a terrible comment. I would never write what she said,” a Breitbart employee told CNN. Another echoed similar sentiments saying: "I find it appalling."

It is not clear if Breitbart, which was originally founded by White House Chief Strategist Stephen Bannon, will take any disciplinary action against McHugh.

McHugh is not the only one to post offensive tweets regarding the attack.

"People think I'm kidding when I say this but the crusades need to come back,” Ryan Saavedra, another Breitbart writer, wrote after retweeting his fellow employee, McHugh’s tweet. Saavedra has since deleted his tweet but not before insinuating that the terror attacks will continue if no one takes a stern step against it.

McHugh has also called for the restoration of crusades in some of her past comments. In one of her earlier posts, she called out the Mexicans for coming to U.S. and ruining it because they wanted to be cured of their “retarded dysfunction.”

Some of the Twitter users slammed Mchugh for her blanket statement on a religious group.

When McHugh was hired by Breitbart's Editor-in-Chief Alex Marlow, he announced she was going to “aggressively and insightfully tell stories that are shaping our political and cultural experience.”

Within a span of one year, she was promoted to the front page editor, despite the fact that she has been flooding her Twitter page with racist rhetoric ever since she started working for Breitbart, Raw Story reported. There is no culture or ethnicity that she did not go after. Through her tweets, she has attacked Muslims, Mexicans, British, Indians, Europeans, Latin Americans, immigrants and so on.

Breitbart is not “a hate site,” contrary to what the popular opinion might be. However, one of the authorities of Breitbart UK, Editor Raheem Kassam, has tweeted calling for internment camps in Britain after the London attacks, which raised many eyebrows, Marlow told NBC News, earlier this year.

Breitbart News continues to be regarded as the extreme right-wing news website which often promotes hate speech.
