Montgomery is a little different from other places. Instead of feeling totally depressed, like he did before, Griffin feels a little more hopeful. This is, after all, the place where Dr. Martin Luther King Junior had his congregation and the site of the Montgomery bus protests. If nowhere else is seeing progress, at least Montgomery is trying.
Griffin doesn't get the white people here, because everything seems calm on the surface, but it's obvious that they just want black people to be violent so that they can claim self-defense.
The "hate stare" is in full force, and even when Griffin tries to smile at some ladies right after church on Sunday, they stare him down. So much for brotherly love.
