My answer actually didn't mention anything about watching over you to ensure that you don't inject lethal poison. I was talking about why I personally would not kill myself or ask anyone else to.

But yes, if I think it's wrong to intentionally kill a human, it follows that I neither want my government supporting it, nor for others to mistakenly think it's fine. Morality isn't something to "keep to yourself".

Presumably you think it's fine to intentionally kill, in certain special cases? Could you do the opposite of keeping your morality to yourself, and tell me what your exceptions are? (I'm wondering, for example, if it is just consent? If so, can someone buy that consent?)
