I haven't watched the video and don't plan to (from mod RainandSadness' post about it, it was clear to me that he never intended on presenting the site and community in an honest way) but I think it's reprehensible for someone to hold the view that certain people aren't "good enough" at being suicidal, they should have just CTB'd by now, etc. The guy who made that video doesn't know you, he doesn't know your story or the challenges you face, he has no idea of the level of thought you've put into CTBing, or anything else about you.
When some people hear "suicidal" it's like they forget that there's a whole human being there, and they immediately shrink them down into these tiny little boxes that fit their narrow view of what suicidal is. It's an extremely outdated view, and I wish by now more people knew that just hearing someone is suicidal doesn't tell you anything else about them.
I've been here for a long time too. I have very specific and carefully thought-out reasons for still being here, and this community has been a huge solace to me in the meantime. So no, no one ever has the right to judge whether you should still be alive, nor whether you should still be on this site. Anyone who holds that view probably knows little to nothing about the reasons you're here.
