I pick minorities for another reason ... they usually had to work harder to get where they are now.
I am not really pro quota in commercial fields. I would however, on a superficial-skill level prefer a minority. In the end I test them anyway and if they don't perform we need to find a way to improve their performance or part ways.
So no, I would not pick a person purely on an ethical level, I would not discriminate them either. Same goes for people with disabilities. People in our field already have to be smart and a minority has a whole different system to fight against as well .... they are probably determined and I like devs with focus.
Besides ... I often like their food gg and they know where to get the good stuff ...
