I've encountered so many people who simply feel out of place with their DNA ethnicity or current family group. For instance, many Americans have so many intermarriages between ethnic groups in their heritage that they identify as "American," yet others relate to the ethnicity of their surname or the ethnicity of some family member who dominates the group. (In some cases learning little about their other lines.) Others cannot relate to any of their lines.
I consider that memories from other lives, DNA, and other factors may result in feeling yourself to be, say Greek, rather than Irish. There are people who have never felt they belonged to the family they know though they certainly were born to the parents they have.
ASK YOURSELF HOW ALIKE OR DIFFERENT YOU ARE FROM THE STEREOTYPES OF AN ETHNICITY. What ethnicity were you raised to be part of?
DO YOU LIKE FOOD THAT IS OUTSIDE OF YOUR CULTURE OF ORIGIN OR UPBRINGING?
DO YOU SEEM TO GRAVITATE TO OTHERS FROM ANOTHER CULTURE, feeling more comfortable with them?
Multiculturalism is apparent in so many countries, especially the United States and Europe, and it brings challenges but also some wonderful sharing.
