I doubt many of us are experts in one or more suicide methods so, on the face of it, probably very few of us are qualified to be able to advise others on actually how to do it. A lot of the time, I wonder if we're just regurgitating what we've already read on here. So, in that way, not advising people isn't exactly witholding information from them. It's encouraging them to look at the source material here themselves. Which I think can only be a good thing.
Why leave it to regurgitated, maybe half remembered interpretations of the source material? So- I don't think there needs to be pressure to provide method information that's already here. A lot of the time I avoid method specific threads because I don't feel knowledgeable enough to respond.
Also- questions like: 'How should I kill myself?' shouldn't actually be asked here at all. We can't be expected to make such a decision for another person. Either whether they should kill themselves (in my opinion, they shouldn't if they need other people to tell them what to do,) or, how to do it. All methods carry risk and, assisting a suicide is illegal in a lot of countries. I think it's too much to even expect others to advise on such things. The megathreads about methods are here for people to be able to make an informed decision on which suits them best.
As for who is justified to have ideation and act on it. I'm not sure it's exactly hypocritical for you to feel as you do. Part of it may be well meaning caution. We simply can't fully tell what sort of state someone is in on here. It's hard to relate our whole life history/ experience. The way our brains work, if they still even can be changed. How much hope we have left. To wish death on everyone to me seems more disturbing! I guess it makes sense from a promortalist point of view but only a handful of members are promortalist.
Maybe it's that you're pro-choice but with a pro-life bias. In that- it's worthwhile for people to make their best effort at recovery before choosing to exit. But then- maybe it would be good to figure out why it's ok for you to reject recovery but, not others. Would your reasons seem justified to all?
Really though- I think you're probably just feeling concerned thinking: 'I hope you're sure about this.' I probably also think that a lot when I see goodbye threads. I suppose ultimately, it's the: 'Is there another way? Could they have lived to overcome whatever it was?'
But then- even if they could, I think the more important question is: Should they be obliged to- even if they didn't want to? It maybe depends on their situation. Those with dependents (especially children,) I tend to think probably should make more effort to try. Those free though- who are they trying for? Not themselves anymore. Is that even sustainable?
Plus, I'll openly admit that I'm selfish. I have to remind myself that I'm pro-choice and if I do truly care about someone, I should want what's best for them. If their life is mostly suffering with no hope left in them for improvement, I can't justifiably wish that for them. I'll miss them though- if they made my life that little bit brighter for a time. Selfishly, I'll want them around still for my sake but I know that's unreasonable to expect that of them.
