White Boyfriend sends memes with the “N” word in them...

We are an interracial couple, Black/White, and he sends me funny memes all the time which I love. However, sometimes those memes have the “N” word in them. I want to talk to him about it but I don’t need it to be a “thing”. He’s never said it. He dislikes the word, but I can admit the memes are funny. I can also admit that there’s a double standard playing out here because of his race. If a black person sent the same meme it wouldn’t bother me but because he sent it, it does. Am I being totally ridiculous? Should I just let it go? Talk to him about it? Am I just dealing with my own internal bias?

To clarify I don’t say the word or promote others of any race to say it. We’ve talked about how our kids will grow up and what they may be exposed to. Education of the word is key but I just don’t like the memes.
