When I was in school, there was an annual trip to Chicago. Museum of Science and Industry + Shed's Aquarium(which is awesome beyond words), plus a couple other places that changed every year. Every year a permission slip was sent home for kids who wanted to go, with a list of the stops for the year, including where we would eat. This was not hard to do, and we are talking a significant all day trip(5 am leave time, return after midnight). If a parent had an issue with any of the stops, they could simply not agree to let the kid go. See how easy this is. No one is saying that I have seen that the trip was inappropriate in itself, only that parents should have been able to make the choice whether to send their children on the trip. This is the point you have still failed to comprehend. it's not parental ability to veto trips, it's parental right to not send their child. It's a real right, and belief in this right is not a conservative position. And you have yet to address this, instead making things up, and blowing things out of proportion, just like you claim this parent did.
