My experiences of home brewed stuff from all over Latin America and West Africa disagree with your theory.

Drink it, you'll be fine!

The most common liquor in West Africa is palm wine, which is not distilled and so methanol does not form. However, West African countries fairly regularly see cases of drinkers going blind from homemade distilled beverages, I would be very cautious about the provenance of any strong liquor offered to me.

In my experience with Latin America, much of that homebrew was produced by the local experts and most people don't make their own moonshine.
