But it should also be looked at as a slippery slope, if a government can tell you what medical procedures you should or should not accept then that is when a problem does come in. It does apply to doctors as well. It is your body you get to decide what medical treatments you allow and which you deny.
You are using two classic Rhetorical fallacies (slippery slope and strawman), and your argument is totally misguided. The government of Italy is not deciding what treatments can be denied, it is saying that a person has a right to informed choice, something violated by Watchtower through forcing the refusal of blood by theologically incorrect doctrine, and misinformation on blood.
