@renwillis @StillIRise1963 it's not a slippery slope argument if you are just taking someone's actual logic and working out the full implications of it. Something is only a slippery slope argument if you can't demonstrate a mechanism for movement down the slope. Maybe before swing around logical fallacies you should actually learn what they mean.
Speaking of which, if you want to argue that way, you're shifting the goalposts. Your initial argument was a justification for controlling the behavior of people by not letting them make poor health decisions if they want to because you somehow think that will be "contagious" to the people around them, and because it will put strain on society to support them and so society gets to determine what they should be able to do, and you concluded by saying that everyone is connected and therefore we should be able to control even the personal bodily autonomy of individuals with regards to their health care. Now you're changing the argument to just be about one about education. I'm sorry but I don't buy that. Trying to use the vague interconnectedness of people and some notion of social contagion to control people's personal health decisions is actually a very fucked up point of view, and one you hear a lot of conservatives touting when they talk about abortion or trans health care. And the logic of the idea that if someone messes up society has to support them, so society should be able to control what they do is absolutely applicable in a broader way as well.
