Do you ever think racist things but keep it to yourself?

I’d be interested to know how common it really is, but who will admit to it? If you do, is it based on personal experience?

One time in college I was walking home by myself late at night when I saw a group of young guys coming toward me. At first I thought they might be black or Hispanic and I was like “oh shit”. Then as I got closer I saw they were Asian and I breathed a sigh of relief and thought “Asians are the least-scary race.”

I don’t think this was based on personal experience as I’ve never had a bad run-in with a black or Hispanic person, but it was based on my understanding of who causes trouble where I lived. Based on stories of students being mugged by Hispanic assailants. Based on stories of black teenagers swarming BART trains and stealing phones out of riders’ hands. I couldn’t help but have those things in mind when walking alone at night.

So…there’s my story. Anyone else willing to admit to prejudice?
