I am so going to be flamed, but this is a touch over the top.
Yes what he did was wrong. But there is a large difference between a sadistic child sexual abuser and a teenager who made an error of judgement (albeit serious). Reading about the case, it seems to be non-violent satutory rape. And as for grooming, the victim initially said she was 16.
His own country has judged that he has been sufficiently punished. He can have a life equal to others. That includes marrying who he likes (or who wants to marry him), having a career and having a child.
People seem to relish denigrating him. He was probably hoping his child would never find out, or could be told at an appropriate time/age. That would impossible now. Also the victim in this case would very probably never of heard of him in the Olympics, if such a fuss had not been made.
This argument about caring about either his child or the victim seems to be ill-thought through. Nuance and empathy instead of raging on the Internet.
