If I may give some advice to the Liberty movement on issues like this, even though, believe it or not, I'd actually end up voting against a ban like this, the LM would sound a lot better to potential "new recruits" by saying even though this is not the proper role of government, it does bring up an issue that is plaguing our society and since the LM promotes voluntary community-based education advocacy (or whatever) over government laws concerning these types of issues, the LM movements needs to step up and start warning and educating society about the dangers of eating a bad diet, such as Happy Meals (ie slow death meals).
