This can go on forever (But will probably stop after Sunday (American time)
)
So Bret Hart isn't going to be at Wrestlemania, I personally don't think it's that big of a deal. If he does show up, yay, good for his fans that would like to see him there, if he doesn't show up, that's fine it's his choice, however he might lose some respect of his fans, but that's his loss.
People should understand that their favourite stars have the freedom to make the choices they want to make, you don't have to agree with them, nobody can change how somebody thinks, everybody makes mistakes, everybody has a flaw.
