A group of open carry gun activists who protested Saturday at Dealey Plaza in Dallas filmed a bizarre, more-than-10-minute video of their demonstration and posted it to YouTube.

One activist appeared on camera to explain that the group, which the Dallas Observer identified as Come And Take It Dallas, gathers every third Saturday of the month to pass out Second Amendment literature. The same speaker then went on a rant against foreigners and refers to President Barack Obama as a “usurper foreigner” born in Kenya.

Later, the camera focused for an extended period on a preacher who was sharing the Grassy Knoll with the activists. The person behind the camera can be heard repeatedly saying “Amen” in response to the preacher’s condemnation of a “sexual charged society.”
