I don't disagree with you, but the statement you made was "But I don't want a government having any opinion on what people put into their own bodies."
I'm not shifting the goalposts, I'm pointing out that statement, as written, can be read a different way, and that actually you might want the government having opinions about what people put into their own bodies.
Government regulation has everything to do with what you're talking about. You're saying the government shouldn't regulate what people put in their bodies and I'm saying the government should regulate what people put in their bodies. It's not that different.
I don't think you intended it, but this is shifting the goal post.
My position is that I think an individual has the right to choose to kill themselves by any means of their choosing. Which means if someone chooses to drink a cup of bleach, I don't think the law should step in to stop them.
Murdering someone by offering them bleach disguised as something innocuous is a completely different matter that has nothing to do with what I am talking about.
