The point of the picture is that the people of Lewiston are protesting the exploitation of the immigration of Somalis to Lewiston by a bunch of racists and antisemites--the World Church of the Creator (I will not put up a link to their website--the last person who did had their posts pulled and was banned, but you can find it on a google.com search). It should be noted that none of the World Church of the Creator members who showed up at the rally (their leader, who was supposed to give a speech in Lewiston, is cooling his heels in a Chicago jail awaiting his detention hearing on solitication of murder)are from Lewiston.
They actually look like the sea of brain-dead, pc, new-age, starbucks coffee drinking, anti-gun, anti-law enforcement, anti-meat eating, anti-Christian, soccer moms and dads I see on the left-coast.
I cannot stand that whining, insipid, arrogant, complacent, tranquilized mentality.
