Why do so many African Americans sound like they hate Caucasians?

I am Mexican, and my mom is from a city that used to be part of Oklahoma. I have been doing ancestry research on my maternal side, and we are 17% black and 13% European. I am pregnant and my husband (who is full Mexican) is getting a paternity test just in case, because of the European percentage. He just wants to make sure that the child is his. I am furious at him because I told him that my family is mixed and he still is acting like this.<br><br>I am on Facebook, and I posted that I was pregnant and overwhelmed. I got the following messages from my male and female cousins:<br><br>I am Mexican, but I am black like you. I am so happy for you, and you need to ignore your husband and just enjoy being pregnant.<br><br>They are jealous of you because you look black and they don’t. Keep smiling and ignore them.<br><br>The messages were from my black cousins. I honestly am not mad at him for wanting a paternity test, but I am upset that he thinks my family is basic white people and that I am not mixed African American like they are.
