A post to an anti-immigrant Facebook group went viral after some members believed a photo of six empty bus seats were actually women in burqas.
According to The Guardian, Norwegian journalist Johan Slattavik posted the photo in the group as "a joke" because he was "interested to see how people's perceptions of an image are influenced by how others around them react."
Reactions to the photo in the "Fatherland First" group ranged from expression of fear to expression of hate among its 13,000 followers.
Some comments included, "Ghastly. This should never happen," "Get them out of our country--frightening times we are living in," and "I thought it would be like this in the year 2050, but it is happening now."
Norway's Antiracist Centre issued a statement saying that people plainly "see what they want to see--and what these people want to see are dangerous Muslims."
Norway recently restricted the wearing of burqas and niqabs in some public places.
