I was raised with a high sense of my ethnic heritage, and I would not have wanted it any other way.
I am very proud of that.
The older generations of my family only married other Italians. I think one of the main reasons for this was because of the neighborhoods they lived in were like an extension of the old country.
This is not the case today.
To be in touch with our history (if possible) is a good thing. There is nothing wrong with taking pride in being Irish, German, Italian, Mexican, Jamaican, Asian, or whatever you may be.
In most cases ethnic festivals or holidays are shared and celebrated by all kinds, not just that particular group.
People need to find the middle ground. I share my ethnicity with my friends, and they all seem to love the fact that I do. My wife is Mexican and loves having the experience of her families culture as well as mine.
The key is keeping it all in perspective. I can feel a special connection to one group of people, but still want to connect with and experience the dynamics of all the others.
