We do not know whether he was under the influence of any mental breakdown. If I say two plus two equals four, am I wrong mathematically? You'd say no. What if I told you I haven't taken lithium in months is my answer no less correct because of my non usage of my medication? Point is you can still make rational judgments and irrational judgments independent of your mental disorder. What red flags it are things that are outrageous and indicative of mental instability. My point is just because Kanye is bipolar does not mean he is free from scrutiny. He can still be under medication and still make stupid comments. I actually work with patients with mental disorders for a living.
And I told you... If he apologizes later then I'll make no issue of this. For now, he's definitely wrong.
