She’s not expressing remorse, she’s selfishly scared for herself.
Remorse requires accountability, not excuses and projection.
She made a racist, hateful, hearsay statement and now that it might affect her she says she can’t be hateful because she’s “gay and biracial.” That’s the definition of dodging accountability.
I like your question! To me it starts with a real apology without excuses. Real apologies are generally short and put one in a vulnerable situation, like
“I’m sorry for spreading these lies, they aren’t true and I did it from a place of ignorance”
No “I didn’t mean to,” no “I’m not racist, I’m mixed,” and so on.
