But I didn't even say anything about yellow in my original comment, that's what I don't understand
I said his oc is practically a lego 😪 he brought up the yellow part to me, it's not like I brought it up first

Exactly. Racism is a very serious thing, and he shouldn’t be throwing around the word just because Jazzy pointed out his character has yellow skin. It’s not even a real person.
And her comment was literally not racist in any way.
Like you said, he’s making a mountain out of a molehill.
