"People of a different time"? I really don't think this has much to do with her generation. BS is definitely not a typical person and hasn't lived a normal life-- nor would I say she's particularly representative of her generation.
It's much more a matter of her Famous Person bubble. If you're famous/talented enough, a different set of rules apply to you-- and apparently rightly so, in her perspective. Whether she'd openly acknowledge that or not is another matter. She may not even be aware of what she's doing. I doubt she would so blithely excuse child sex abuse from some random "nobody".
Anyway, didn't like her before, so there's no need for me to "cancel" her. She was never especially "valid" to begin with!
