He's diagnosed with bipolar back in 2016 and talks about refusing medication because it messes with his ability to create/be creative.
It's possible that he's exhibited symptoms for far longer but it was brushed aside under the guise of kooky genius. I mean, the Taylor Swift thing was, what, 2009?
It seemed pretty fair at the time, like I remember being confused by why it caused such a media furor. You could disagree, of course, but you could also see given the circumstances why someone would say it.
I'd definitely say it was fair at the time as that was around Hurricane Katrina and the vast majority of the most affected people at the time were low-income black people. IIRC some parts of the 9th Ward are still yet to recover from Katrina.....and that was 17 years ago.
