Don't get me wrong, it's still not ideal and definitely something I constantly have on my mind when it comes to alcest. But I believe him and respect the way he owns up to that past.
As far as neige, why does it matter when he realized he did wrong? The main thing is that he did. He was never heard being publicly racist, and has clearly distanced himself from the band and their ideology.
Yes. And that makes him a free man who has paid his dues to society. His ex-wife is still heavily traumatized to this day and he has a stage, a band, a label, and a platform.
