"Facebook is allowing videos showing people being decapitated to be posted and shared on its site once again."

"The social network had placed a temporary ban on the material in May following complaints that the clips could cause long-term psychological damage."

The US firm now believes its users should be free to watch and condemn, but not celebrate, such videos.

How are they controlling how people react to what they see?

Facebook's terms and conditions now state that it will remove photos or videos that "glorify violence" in addition to other banned material, including a woman's "fully exposed breast."

Idiocy.
