I think the word prejudice has picked up a negative definition that doesn't ACTUALLY exist.
Pre-judging is not such a bad thing.
Creditors, human resource directors, firefighters, doctors, people with common sense, etc... PRE JUDGE.
If I see someone with a blood soaked sweatshirt and a box cutter in their hand outside my peephole... I'm gonna pre-judge them and act like no one is home, call 911, and try to sneak into the garage, start the car, and drive away as fast as possible.
If I see a white person with a Southern Pride flag in their F150 window and they have a mullet and some spiderweb tattoos all up and down their arm...I'm pre-judging that he might not be the guy for me to flirt with or spark up a convo with.
If I see a black person with tattoos all on their neck and teardrops on their face and a tshirt that says "Never going back" on the front and "Soledad Prison" on the back... that might not be the person to ask if they have change for a $20.
Prejudging helps keep us all alive and safe, in its most basic form.
I think that prefrences and prejudging are all fine and dandy and natural.
Discrimination is different from having a prefrence.
