Uh...you can be a racist and still be dating, married to, or even have kids with a person outside your skin color. In fact, most closet racist use their significant other as a shield by saying, "I can't be racist, my gf/wife is *insert race that isn't white*!" For example, white males who fetishize Asian women are notorious for this. Richard Spencer is an alt right white supremacists who have dated numerous Asian women. Thomas Jefferson has had sex with a good number of his own slaves. So don't try to say the tired old "I'm not racist, my wife is half gambian half norwegian."
