I don't see the point in ignoring race, or any other physical traits. It's almost as if when it comes to survival some people would rather be dead than being seen as a bigot or racist.

When the details of the situation you are in start to fit the common parameters of stories you hear that's when you need to be on high alert.

For instance, I doubt most people will think twice if they pass a woman in an alley, no matter how she's dressed. Females mugging and killing people just isn't a thing you hear about all that often. So you take your chances.

Likewise a man of any race wearing a suit is probably not going to be perceived as any kind of threat either.

Could these people be threats? Of course, but statistically it is unlikely.

Likewise, if you are somewhere where a member of a race has never killed anybody, you probably would feel at ease around those people. Or maybe it's an area where crime is low in general all around, then perhaps you walk in peace and freely ignore everyone as a threat.

It has nothing to do with being a bigot or a racist, it's all about being aware of past patterns that have led to people's deaths and avoiding them.
