This isn't atypical, actually. May biases are wired into our brains such that we're not particularly aware of them - they're just part of how we think. Back in undergrad, I took quite a few psychology courses and one of the instructors pointed us to an interesting research tool being used to measure subconscious biases. In basic, it works by having the subject look at images of diverse people and then being instructed to tap a key to associate that face with positive or negative words. Subconscious bias is then factored based on a combination of time and errors. Most people who take this test do not score bias-free.
There's an important caveat with this though - while we speak of bias as if it is a bad thing, that is not necessarily the case. All humans are biased. The real question is how those biases meaningfully impact our behaviors.
Experiences create the subconscious.
I know I'm biased towards one particular group here in my city. That group has high crime rates, and scary neighbourhoods. When I meet with a person from that group outside of that context, I'm fine. But within that area of the city, too many news stories of gang robberies, random beatings, and the likes have me locking my car doors while driving through there. Sometimes I think it's just common sense on my part, yet other times I think I'm a racist jerk. It is a troubled community.
All others, not a problem, unless it's deeply hidden in me. I would have a hard time counting the number of ethnic restaurants I've been to.
So judging the individual comes first, or should. When that individual happens to be a recognisable minority, it's certainly not clearly racism. I would avoid anyone with a nasty criminal record, or a history of anger.
