if you're happy in the relationship that you're in, then who cares what other people think? i have been in relationships with other races and i couldn't care less what other people thought. Just make yourself and your other happy and ignore the other people. They'll learn to accept it sooner or later.

My parents were all about me being with another Vietnamese girl and kept pushing me to date Vietnamese girls only but they realized that i dated more other races. They accept it now and dont care what kind of girl i bring home.
