> Those parents need to find solutions that don't involve forcing their morality on others

I believe forbidding these ads is morally good, but it's not just morality. It's knowledge backed by studies:

- children are easily influenced

- burgers cause public health issues that harm the individuals, and cost greatly to the society in healthcare

It's not a stance like "I believe women should not abort because God" (to take your example). It's a law aiming to reduce costs and and improve public health.

This laws doesn't prevent parents from speaking about burgers to their children, and doesn't prevent TV from speaking about them neither. It's not a freedom of speech issue.

There's an imbalance between the power of the big corporations and the power of the individuals and this law pushes the needle a bit towards the individuals. You the individual freedom defender should be happy with this :-)
