You're comparing a specific, high-heritability physical trait (fast twitch muscle fibers common in West African ancestry) with broad, complex social behaviours ('intelligence', 'emotion') that are massively shaped by environment. This is a false equivalence.

We use the same logic for everyone: Swedes are taller than Pygmies due to genetics, Swedes have higher literacy rates due to historical and economic factors. Applying this consistent logic isn't an excuse, it's basic science you're failing to grasp.
