If my son sings out of tune, I'm going to deny he's mine.
Oh that sounds weird to me. Why would you do something like that?
I hate bad singing.
It is wrong to deny your kid for not being able to sing great. You can get them singing lessons or just let them find a new interest.
I want my kid to be a singer. Nobody is going to stop that.
You should pressure your kids to do what you want them to do with their lives. They will become resentful and rebellious towards you.
