I care as much about her as I've cared about any pop diva over the past 40 years; not at all, other than rolling my eyes about how important so many people seem to think they are, and quietly looking forward to the day I never hear about them again. They're not for me and that's fine. If little girls like her, that's also fine, but the screaming fanaticism they attract has always baffled me.
I've never heard a single one of her songs, and have zero interest in changing that. So, no hate, just apathy, with a bit of frustration at the stupidity of the masses. A normal day, in other words.
