Dealing with ignorance

Hey guys!! I know even though its 2018, there is still a lot of ignorance and straight racism in our society. How do you deal with it when its coming from your inlaws? Not so much racism, but when they say or post things that are blatantly ignorant and offensive. Im black, my entire family immigrated here from Jamaica. My husband is white. We are expecting our first child. I bite my tongue all the time, but Im getting fed up and really want to block her (its mostly the mom) from like every aspect of my life. No, I dont really talk to my husband too much about it. He deploys quite often. And I guess I have started noticing it more often recently bc people are talking more about whats happening now then say 5-10 years ago. I know deep down she is a good person, but I feel she has blinders on and stereotypes races and doesn’t understand what people are fighting for and doesn’t care.

Since we have been expecting, she makes little comments like oh yeah you plan a vacation we will take the baby. But I dont want my child to be around views like that. But yes i do know i cant keep her from her grandchild! 😂

But how do yall deal with it. Do you just always stay quiet, hold your tongue? Do you have your spouse say something? Or do you say something yourself and risk tension in the future?

Thanks yall!
