Yeah I mean she is basically indirectly making that same point. Her statement is not a put down of Twain. She doesn’t see herself as racist and she doesn’t do things in the spirit of putting down marginalized groups but she is acknowledging that she (like Twain and literally every other comedian and satirist) is a product of her times and will have hundreds of jokes or bits that don’t “age well”

I see it as a statement that any comedian who takes risks will say or do something that will cross a line in someone’s mind now or in the future. No one is immune, even the most socially conscious individual.
