When Muslims held a demonstration in London in 2006 in protest of cartoons depicting their founder, Muhammad, many bore signs warning of beheading and death for “those who insult Islam.”

Talk-radio host Michael Savage thought that amid a fierce national debate on whether or not to allow Muslims to immigrate to the United States, it would be worth considering what has been happening in Europe.

So, he posted on his Facebook page photographs of the Feb. 3, 2006, demonstration outside the Embassy of Denmark in London. The focus of protest was the publication of editorial cartoons depicting Muhammad in the Danish newspaper Jyllands-Posten. Snopes.com verified that the photographs were taken at the London demonstration, with the exception of one, which was from a protest in the English city of Luton.

Last night, Facebook removed Savage’s post, explaining the social media site “determined that it violated Facebook community standards.”

Facebook has not explained why it deleted the post, but it provided a link to its “Community Standards” page, which lists “hate speech” as one of its prohibitions, along with “violence and graphic content,” and nudity.

Messages in placards held up by the London demonstrators included “Behead those who insult Islam,” “Freedom go to hell,” “Europe. Take some lessons from 9/11″ and “Be prepared for the real Holocaust.”

The Facebook post on Savage’s page included text from an email that has circulated for many years:

Why would anyone think that we should be at war with such nice, peaceful Muslims?!
