I grew up in an 99% white town. With one percent asian community, I did not even realize who I am and understood my roots or culture. I grew up watching T.V with mostly white actors having white issues. With only exposure to a white based culture, it is no wonder I have lost my roots and even my identity. By being rarely exposed to my culture, I and many others like myself had built a disinterest in my own race. Some would go even further and say, they have a dislike for their own race. Others would go further and is adamant to never want to date their own kind. Many would criticize their own race for whatever reasons they can find.
If the above describes you, then you have a lot of soul searching to do. You are, by genetics, identified by your race. If are embarrassed to be your race, then you will definitely have a difficult time relating to others. To be your authentic self, you must accept and appreciate who you are and where you came from.
Your exercise is then to interact and associate with your race and you will notice a lot similarities between yourself and your race.
Once when you can accept and appreciate your race, it will then be easier to relate and date others. You, of course, do not have to date your own race, but you will not be embarrass by it, either.
