Too often people confuse one's "opinion" with being judged.
Everyone is entitled to have their own likes and dislikes. In fact it's human nature to make snap decisions on a wide variety of things (without doing a deep dive) to explore something or someone fully.
You see/hear/ read something daily and immediately say I don't like that. It's human nature.
Someone for example may see a person walking down the street with bright green hair, tattoos on their face, and ten earrings in each ear and think to them self; "that guy is weird". However he may be the nicest guy you'd ever want to meet.
Not liking the way someone looks or being uncomfortable around them is not "judging" unless you discriminate or somehow have the power to control whether they get something or not.
Lets say he tried hit on a girl who thought was cute and she shot him down or chose not to speak back to him.
Each of us gets to choose our own friends, lovers, and spouse.
Now the guy with the green hair may have the attitude that he hates people staring at him or he feels people "judge him" for the way he looks. However it was his goal to stand out from the crowd!
To "stand out" means to be noticed. People who choose not to "conform" should not be upset or surprised when people do a double take. Anyone who is not "the norm" will draw attention.
In other instances people look at other people in various situations such as teenage pregnancy, alcohol or drug addiction, or a prostitute and make a snap decision about them based upon their core beliefs or personal experience having dealt with someone or heard about a person in similar circumstances. It's unrealistic to expect everyone to automatically empathize.
The first thing most people do is tell themselves that they would "never" do such and such. It's how we identify ourselves in the world. That's normal.
Having said that it's not unusual to find ourselves doing something in the future we swore we'd never do. :)
