No it isn't. Even three month old infants already show preference for people of races they are most familiar with. This could include two or more races depending on what they're exposed to, but it's usually going to be their parents.
It takes socialization to overcome the evolved preference for one's own race (or races most familiar), as it stems from evolution in a time when seeing someone of a different race could very well mean you were in imminent danger. Even in today's world, there are plenty of places where that is the case and caution is warranted.
While it's dumb to hate people solely because of their race, especially after they show they aren't acting in conformity with negative stereotypes of that race, it stems from an entirely natural instinct.
