Goodness. If this was the US, I would be losing my mind over such legislation. We must not convince the law makers that video games can be beneficial. That puts the wrong emphasis on the conversation. The emphasis must be, you have no jurisdiction when it comes to raising children. Your laws are invalid. Even if video games are detrimental, you do not decide what is the best interest for a child, the parents do.
Speaking as a parent of two kids, I mostly agree, but also think that some amount of law-making in the interest of children is appropriate and fair. Drawing the line is the interesting part.
Like you say, what is considered a parenting decision? Reasonable people can have a discussion about this.
But I'm shocked how many people seem to think A) the government actually should make parenting decisions, and B) that things like banning child abuse is an example of the government making a parenting decision.
Neither of these things are reasonable, and so the discussion about what qualifies as a parenting decision will also be unreasonable.
