Parents of Biracial Children

so, this exchange is about parenting biracial children and i want to know how "accepted" u feel in ur community? where i live it is pretty common to see inter-racial couples ( mostly black men with white women) and plenty of biracial children to say the least so i personally feel like i fit in and am accepted in my community. i have a biracial son(black and italian) and am pregnant with a little girl-by the same man-my husband/ hes black,lightskinned, and im italian. my son looks just like his dad but a softer version. so theres no denying his ethniticity. everybody always wants to know what hes mixed with. his dad says our son is black(like when they ask for race on apps etc.) but i always mark all that apply. anyways my issues havent really been being accepted in my community its more like with my family. anybody else in a similar situation??? my dad is fine with black people in general but is against interracial dating and procreating(sorry for lack of a better word). now luckily ive been with my husband for seven years and my man has had to prove himself to my dad and my parents love him and our son and are excited for their newest grandchild to come at the end of the month!!! hes come a long way---seriously. heres the scoop- my sister moved out at seventeen- with her boyfriend (and lied and said she was moving with her best friend kristy) plus her man was black and she hid the whole relationship, got pregnant, had her son, never told our parents, and she gave them HELL when she was a teen before she moved out. so my parents already didnt like her- i know its sad-. fast forward ten years--- my nephew just turned ten and have never met my parents- his grandparents- and they live in the same city!!! my parents hate my sis from all the pain and hurt she caused many years ago and my nephew suffers cause he doesnt know his grandparents. plus her man called my mother all the names in the book and threatened my dad, so they really want nothing to do with my sis but she still wants to reconcilliate the relationship. i think its pointless and she needs to just stop. but she makes me suffer and feel bad cause our parents still see me, my husband, and our son- but we never caused the hurt and cussed them out or threatened them. my parents are just soooo damn stubborn and im in the middle. ive been trying for years to get them talking again but they dont like how she lied and covered up her relationship and pregnancy. i was completely open that my man was black and i waited till i was eighteen etc. so somehow that makes it better in their eyes. i guess. this is getting long so im gonna wrap it up, but just curious- what is ur experience- if any- dealing with racism in ur community- or even worse- ur own family?????
