YMMV / Sixth Column

• Fair for Its Day: Heinlein, reportedly, believed that he removed the racist elements of the Campbell's story. Imagine what the original was then.
• Overshadowed by Controversy: If you've heard about this book (which isn't likely), it's probably in the context of it being a genocidal fantasy in which the heroes annihilate everyone of Asian descent except one of their own at the climax.
