Is it racist? I don’t think so because it’s generally okay to make fun of white people. And the teasing here is pretty gentle and obviously not written from a place of hatred. The author seems to just think that her white friends are generally kind of odd and amusing, in a harmless, non-patronizing sort of way.
For me, numbers 1, 19, 23, 24, 28, 29, 35, 42, 44, 50, 51, 52, 53, 56, and 76 strike close to home. That’s quite a lot of them. I must be really white.
