Earlier quoted context omitted.
Yeah, it's really not up to the parents to raise their kids. It's scarry how we get to this point where people write this kind of shit with a straight face.
Raising the children is supporting them, and helping them get over the fear of performing publicly (or whatever). It's not their job to be the technical coach of whatever they want to learn.
Would you apply the same to, say, mathematics? Or chemistry? Or programming? Do you think the parents should not give their kids feedback on these subjects, and instead leave it to the teacher (aka technical coach)?
