Mixed women on here?

I'm a FTM currently 23wks pregnant and I'm just curious if any are on here I'm Black/Mexican, and Brazilian and I feel like myself I get ignored or discriminated against others because of my mixed ethnicity..mainly (no hate) white women I asked a question about if any mixed woman like myself had a son with their hair wondering if my son will have my hair instead of their fathers (who is Mexican). A woman then comments " it shouldn't matter, since you're half black it's most likely going to have that thick hard to tame hair" and it really hurt me..I know mixed hair is usually hard to tame but it's unique and beautiful...why can't a biracial woman or family be equal as others??
