I Have No Problem With Interacial Relationships

With all the racial division in America how do couples in interracial relationships handle it?  The guy I'm seeing totally avoids conversation about race and he acts as if there's nothing going on. If we're watching television something comes on about racism he'll switch channels. Its getting to a point where I'm thinking do I really want to take this further. And I'm not sure how to bring the conversation up because obviously he doesn't want to talk about it.  Other than that he's a great guy. 

I am a mother of 2 young black men one's a sophomore in college and one is in the Air Force . His son is Caucasian and there's no way he can understand how I'm feeling right now. I just don't want him to shrug it off like there's nothing wrong. ☹ I really don't know what to do.
