These white boys are having a hard time of it. First, Mississippi Gov. Haley Barbour waxes nostalgic about the white supremacist Citizens Councils.

"Marvel Studios declares war on Norse mythology!" they proclaim, before urging us to "Boycott Thor!" Listen: boycott it if you want because, judging from the preview, it looks way dumb. But as to the "insulting multi-cultural make-over" of a movie version of a comic book rendition of a Norse myth: Change is hard, you lost the war, get over it.
