I fucking despise people who say claim they don’t judge people by their looks, what utter bollocks. Unless they have some wires crossed, or like you said, are visually impaired, it’s basically impossible to not do so.
Judging in general is not a bad thing in my opinion, because your judgements or assesments can and should keep changing when you get more information.
People are generally full of shit when it comes to these things. Virtue signalling...
We have to judge our world, experience and feedback makes us better or worse at it.
