The Human Baseline Alliance is a political advocacy group of approximately 7,000 members that occupies an uncomfortable position in GLMZ's political landscape: they advocate for unaugmented human rights without the religious framework of the Unbroken Flesh Tabernacle and without the anti-technology extremism of movements that want to abolish augmentation entirely. The HBA simply argues that choosing not to augment should not be a social or economic death sentence.

In GLMZ, the unaugmented face increasing discrimination: employers prefer augmented workers, social spaces are designed for augmented perception, public services assume BCI access, and the cultural assumption that augmentation is progress makes the unaugmented seem backward, stubborn, or poor. The HBA campaigns against this discrimination through legal advocacy, public education, and political lobbying for 'baseline accessibility' — the requirement that public services, employment, and social participation remain accessible to unaugmented humans.

The HBA is politically moderate and deliberately secular, which distinguishes it from the Tabernacle and makes it palatable to mainstream political observers. It doesn't oppose augmentation — many of its members are augmented themselves, advocating for the rights of unaugmented family members or out of principle. This moderation makes the HBA effective in legislative contexts where the Tabernacle's religious fervor is counterproductive.
