alt Hacker NewsFrom what I understood ethanol and methanol form an azeotrope and boil together at a mixed temperature. And the going blind stuff is just prohibition propaganda both to make home distilled alcohol seem dangerous and to scapegoat the fact that the government was actively poisoning "industrial" ethanol.

I don't think so https://en.wikipedia.org/wiki/Azeotrope_tables
this is dangerously wrong in several dimensions
methanol and ethanol do not form an azeotrope with each other, they only (both, each) bind to water. that's why separation of methanol and ethanol by holding key temperatures works at all.
furthermore, the azeotrope effect only becomes relevant at concentrations beyond 90% alcohol. so when you're producing pure methanol and ethanol, then distillation won't cut it beyond 90+% as water+(m)ethanol then *at these high concentrations* boil and evaporate together. that's the grain of truth in your statement.
last not least going blind from methanol is _very_ real.
