Good question.
On the one hand, I firmly believe that an easy and peaceful death should be available to anyone who is capable of making that decision. If a capable adult, who is not being coerced, has considered their options and is sure they want to ctb, they should be able to access the information and emotional support they need to go through with it.
On the other hand, it gets complicated fast. Who's to judge if someone's "being rational"? Where's the line between "you're being impulsive, wait a few more hours, see if you feel better" - "just wait a few more days" - "weeks" - "months" - "years" - "decades"???
I deeply appreciate a lot of information posted here. But so far I've refrained from discussing methods, even though I've read about them and found it valuable. Feels kinda hypocritical, but eh.
