It depends. but I believe in happiness. Not everyone prefers another race - many people are attracted to others who look similar. However, many people are attracted to differences - someone from another race is exotic and new compared to the "usual" people that they may see around them in their daily lives ... Most people end up picking a partner based on personality instead of just looks - that's the only way to get a lasting relationship that makes both of you happy.
