Oh, I believe you, Shooting Star. If you are that unhappy in your home, then move. I hated the place we lived for the first 6 years after moving back here, but it was where we could afford to buy. It actually exposed my kids to different kinds of people, in terms of income, and that part was good. But, I felt isolated. I've never been much on socializing with neighbors, so I just made my social life elsewhere.
All the research I've read about bi-racial children talks about what you said. Same thing for mixed religious households. I hope my younger son exposes his future kids to Judaism... I worry about that. He was the most religious in our family, growing up, and now he just does what his wife wants. She is not religious, but this time of year makes me glad I don't live near them. On the other hand, they are totally accepting people, with friends from all cultures. My other son and wife will raise their kids Jewish; she grew up sort of nothing/Protestant, with one Jewish grandparent. When she was a kid, she actually lived in a Jewish commune with her parents, because their house burned down and this was the only place that would take them in. So, she's totally comfortable with it.
Compared to most of the kids mine grew up with, my sons are way more down to earth and non-entitled, and we worked hard to make it happen, even when we lived in places where that was not the norm and we had the money to do otherwise.
