I can definitely see why they act the way they do. The thought of someone dying is scary, and they believe we are making the 'wrong choice'. I do think a lot of them have good intentions, even if it's not really helping.
What I think most don't understand is that the reason we CTB is since we aren't left with much other choices, or any at all. But if they take away that 'final choice' from us, what do we have left? Nothing, an empty state with out most basic right of choice being deprived.
Everything stems from them just not having been in our position and knowing what it is like.
