Yes, and I would seriously doubt that many of them claimed to be Christian. Look at how many on this forum wanted to be there, and many wanted to take up arms and take the presidency back. I'm sure a great many identify as Christian who were there in the middle of the chaos thinking they were doing God's will.
"And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
And for this cause God shall send them strong delusion, that they should believe a lie:
That they all might be damned who believed not the truth, but had pleasure in unrighteousness" II Thess 2:10-12
