Border Disorder
On 26 August 2015, the Facebook group "Americans for Common Sense"
posted a photograph (first example above) purportedly showing a fence built along the border between Mexico and Mexico's southern neighbor, Guatemala. The image was accompanied by a query about why it's not "racist" for Mexico to build a fence to keep Guatemalan immigrants out of their country, but it presumably is for the United States to construct a similar obstruction to prevent Mexicans from crossing the border into the U.S.
However,
the proffered picture does not show the border between Mexico and Guatemala. Ironically, it depicts a fence along the boundary between the United States and Mexico in southeastern Arizona.
A second similar photograph (second example above) of a putative border fence between Mexico and Guatemala circulated on social media in March 2016, along with text questioning whether America shouldn't have the same right to build a barbed wire fence (presumably along the U.S.-Mexican border) in order to keep out "freeloaders." That image also has nothing to do with either Mexico and Guatemala:
it's actually a picture of a fence that Israel built in 2013 along their border with Egypt (near the Red Sea resort town of Eilat) in order to keep terrorists and illegal African immigrants from crossing into Israel:
