I'll start by saying my skin is really pale. Like, ginger "burn after 5 minutes in the sun"-white. Thus I don't personally experience racism often (although of course I do notice it around me a lot, because fuck are there many racists), nor do I think it's even comparable to how bad it is for other people. But this one time caught me so off guard, because this woman actually thought she was giving me a compliment and she had no idea how fucked up it sounded.
One of my parents is white, the other is mixed. That side of the family has roots in Suriname. When I told one of my colleagues about it, she told me "wow, then you really got lucky with your skin color!" Like wtf? And here I am, always jealous of my sibling, who can actually walk in the sun without burning up like a vampire.
I often wondered if I was making too big a deal out of it, because it pissed me off. I called her a racist and never talked to her again. Luckily I don't work with her anymore.
