@Walilamdzi I don't think you can really convince them, like others have said, but you can give your reasoning and provide "some" comfort after you have CTB'ed.
@Kikoo Loool Very true, they don't like the truth nor want to face reality.
@headinghome Also, to add to your point, I believe that even those who have experienced it before (some of them, but not all), and then recovered at a later point in their lives may also refuse to understand or acknowledge that suicide is rational. It's kinda like they themselves decide to assimilate into the cult of life.
@EddieAllenPoe That is really well said.
@housecat I fully agree with your last sentence, because sometimes when there is no solution and one does NOT want to accept the result, then suicide is an alternative solution to that, especially if the issue is long-term or severe enough (to the particular person). I don't think society nor others should judge said person's reasoning or make that determination for them because each person's suffering is unique to their own.
@deflagrat This is a really good observation. Too many people have become numb and accustomed to shitty things in life that they even blindingly accept shitty things as positive. I believe if anyone has mental illnesses it's the majority of people in society, whom all (or just about all) are pro-life. It's quite arrogant for the majority of society to then see us (who are not only realistic, but also logical and rational in our decision making and reasoning) as mentally ill. It's basically all about people control for society; if there is any dissent or deviation from what it deems 'normal' or even acceptable within it's bounds, then it labels it as mentally ill or irrational. Society also likes to use the government itself to enforce it's decree both legally and physically while using the pseudo-science psychiatry to manipulate the foolish masses of society (majority of people out there) and media to spread psychiatry's evil grip.
