Rascist or not

Okay so I'm Mexican and my babies father is black. But I live with my grandmother whos husband is Indian so she had no problem. But my mother always makes these little remarks that bother me so much. Just right now she asked me if I can see the baby clear in my ultrasound because it's dark in there and mabey you can't see him. Than I'm like are you fucking rasist? She's trying to change the whole story up now. Like than she claims that she's not.
