He didn't change his mind. He only "changed his mind" to try to keep his job, and it didn't work.
He was only sorry once he got a lot of flak for his pro child rape opinions.
Put it this way - if Andrew Tate all of a sudden said that sexism is wrong and he's sorry for his actions, only once YouTube started removing his videos, would you believe it to be genuine? Or just him trying to maintain his position? It certainly seems like a convenient time to have a change of heart, no?
And he didn't "quit" he was ousted. He "resigned" in the same way Liz Truss did, for example.
Sorry, I have no time for people who want to see children get raped.
