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.

Methanol will certainly make you go blind if you consume it at too high a ratio, it just isn’t a risk when distilling because you can’t feasibly make that happen on accident and it would be hard to even do it on purpose. I think that’s what parent likely meant.
