I'm French, English, Scottish, Welsh, Dutch, Irish, Italian, Spanish and a touch of American Indian. No big deal, I'm a mutt.
My son is almost 3, VERY smart, VERY verbal. He has infrequent supervised visitations with his father. After a recent visitation, my son came back and casually mentioned how Greek is good, not-Greek is not good. When race and culture and ethnicity comes up with my son, I just give the facts- Mom-Mom's this, his father's that, he's both, etc. My son's father is 100% Greek and proud of it. In fact, he goes way beyond "I'm Greek and I'm proud"- he's made comments about me about how it's a shame our son is "only" half Greek, and how he's got such a proud heritage and my side of the family" doesn't even know what we are", etc, and how everything needs to be Greek, Greek, Greek, and if our son doesn't fully embrace his Greek side and forget his other side, then he'll pretty much be disowned. My son's father has some very scary mindsets along the line that Greek is the only pure race. In other words, father's side- Greek- is better, Mom's side- a little of a lot- is something to hide, something to be ashamed of. I expect this... I don't know what to call it... indoctration?... to only get worse as my son gets older. I don't want my son to grow up either thinking he's better than everyone because he's Greek, or thinking he's not good enough, because he's only half Greek.
How do I successfully help my son to learn that ALL his sides are good and acceptable and that his father's side- Greek- is not the only good side?
