Interracial Relationships and mixed babies

WARNING THIS IS LONG 😀

I will ask my question first: Do you believe that mixed children struggle more with their self identities and are somehow less accepted by their parents cultures?

I personally believe that everyone will struggle with something (sexual identity, body image, religious beliefs, ECT.) and we can't control how others will treat us we can only control our responses and we must equip our children to brush off other people's ignorance.

I have been with my boyfriend for a little over a year. he is black and I'm mixed (Mexican and white). we live in Oklahoma and luckily have not had to deal with anything more than the occasional stare or glance from strangers. His parents and mine are very supportive of our relationship and I feel very blessed for that.

A few months ago I thought I might be pregnant and I was talking with my cousin about it and she stated that she prayed I wasn't because that would be terrible. I was completely floored. at first I thought she meant because we hadn't been together long and weren't married (which doesn't matter to me at all). I told her it wouldn't be the worst because we love each other and are not opposed to having a child together. She said that wasnt a problem at all...the horrible thing would be to bring another mixed child into the world. Why would I want to have children that wouldn't look like me and it was cruel to make sure that my children would have to struggle and they would never fit in anywhere and I was irresponsible to bring that into our family. I was literally speechless. I thought she would be more accepting because she was married to an African American man for a DECADE!!! She does not believe that those beliefs are racist. We have not spoken since.

I am still so confused by what she said.
