The "church" posted an explanation of the reasons for the protest in their schedule, but the gist is this:
How do you know how far gone a society is? You look at their social icons. When you look at these gender-confused, haphazard freakazoids then you can plainly see that america [sic] is DOOMED, for real! This is the final generation, and a little concussion is the least of their worries. Here is what they have to look forward to when this once great nation finally falls - for her fall is already started. She is such a big, fat, disgusting, stupid whore that it is going to take a while to fall (brings to mind the comedy routine that Eddie Murphy does about his drunken cow of an aunt who falls down the stairs at each of their summer bar-b-ques as he was growing up). That is the picture of this nation falling slow, steady, hard and sure.
The statement goes on to call Obama to the Antichrist, before describing Cain as "the father of all musicians."
