Em had a breakthrough this visit with my mom's fiance. Em used to have this strange fear of Asian men with mustaches. She's recently overcome that fear and is no longer scared of our favorite sushi chef nor of my mom's fiance. She happily played Legos with him and has even asked about him (and my mom, of course) a few times since they left.
I'm glad she's moved on from that phobia so we no longer have to explain that, no, our daughter is not racist.
