There is a big focus on race nowadays, and it’s not surprising with the rapid globalization. Regardless, there has always been a focus on race, and it happens when any group of people is different from another. People will only stop caring about race when the population is homogeneous, but even then they will find issues with each other.
Each race has it’s own stereotypes, but they tend to forget that people of any race can fit the stereotype of another race. For example, many people assume “thug” gang activity to only involve Hispanics or people of color, but it’s not extremely rare for the odd individual of another race to be part of it.
