Yeah it's a childish thing to demand. So basically because other people were late to the party on a situation that was addressed, that he was made accountable for, that he dealt with, showed penance for and moved on with his life.... now he has to go through it again and again. What's the message here? That you don't get to move on from your mistakes? That almost ten years later if someone new reads about it on the internet they can demand an apology?
At some point people are entitled to move on with their lives if they addressed and handled a situation properly going forward. Especially if it's saying stupid things. If he actually hurt people, okay then maybe we can find that unforgiveable. If it's a tweet from 7 years ago? Yeah I think at some point you lose your ability to demand continuous apology tours.
Again this is being completely misrepresented as well. He did not get kicked off the Oscars. The Oscars demanded an apology and he told them to take a hike. The Oscars' been struggling to get people to host this show and this is one of the reasons why. Nobody wants to deal with hyper sensitive scrutiny from an award show that caters to stuck up celebrity's that can't have their sensibilities offended. And nowadays not enough people watch to make the publicity worth it.
The only funny thing about this is that they probably got Kevin Hart because they were like "oh it's Kevin Hart, he makes the corniest shit ever, he won't offend anybody".
