If I agreed with you (or just don't want to bother with a response to a section) I won't reply. No reason to say anything when there is nothing to say. Is your argument here really going to rest on "I don't really care if it's propaganda"? I don't even have to say anything outside of just repeating your argument here. Propaganda is not a good thing, and if you are exposed to it, or are exposing people to it, you should attempt to end that thing. It is a stain on the ability for people to think freely and develop their own opinions, ideals, and so on. It doesn't matter if you care, what matters is the people who will be hurt, the ideas that die, when propaganda is accepted and freely spread. Unless you are willing to argue that propaganda doesn't do this, or that what you mention is not a form of propaganda, then you have no valid argument. So your opinions and thoughts of highschool being super busy are based on your very unique situation?while you might live for that type of conversations to me it seems like you are going to go for contrarian angle no matter what I will say.
I live and had a quality lessons on the above topics. Propaganda? Perhaps, but I don't really care. Just like I don't care for illicit drugs.
On the other hand I was in school where I didn't even realize that I'm attending AP everything sans history and maths on a level that ended around calc II for CS majors.
Don't present argument, present researched and understood fact. This is how they do it in every other classroom from evolution to astronomy. "The earth has seen X degree rise due to warming in the last year" "It is suspected by these institutions that this X degree rise will cause Y effects." "These activities are known to release X amounts of carbon dioxide." It's that simple. No statements about what you should do, or what you should think, just the facts and definitions that are required to come to your own conclusion on the topic.3. Presenting at least two sides of argument
