As some of "mixed race" these conversations always get weird. Defining a person's race seems mostly exclusionary in my experience. By that I mean, when I'm around a group of people who identify as one of my races, they think I look like a member of the other group (noticing the differences more prominently than the similarities) so either way I'm defined as an other. My family is pretty heterogenous and in a few generations I see it being hard to peg specific individuals as a particular race.
