A lot of your words made sense Queen Bee but I have to disagree with you on one point. ALL topics are debatable. Although I would find 0 support from anyone on QL, and don't agree with it myself, I could make arguments for pre-teen drug use, the example you used.
Everyone in the world thinks differently, has a different set of morality field sticks, and that is why people's opinions will always differ. If there were no for and against opinions for each and every topic that is raised, then there would be a straight forward answer to each one, and our world would already be living in peace.
