I don't tend to cross the street to avoid a potential situation. The closets thing to that is when someone is walking too close behind me and I stop to let them walk past me. But that's not a judgement thing as I do that to everyone- male, female, old, young, single people, groups of people, friends, my kids, strangers- it doesn't matter. Have I judged people? yeah, I'm not perfect, but I tend to shy away from judgements as much as possible and if I have that much of a strong reaction then I will at least make an attempt at approaching said person to strike up a conversation that way the judgement is not based purely on sight alone.
