Oh dear, I'm actually surprised that this thread hasn't been locked yet because it has become such a mess. I will probably regret contributing my thoughts to this topic but I have some time today and here it is:
First, I need to make it clear that what I am criticising are the actions that have taken and not those acting. What I write is in no way intended to be an attack on anyone's character and I want to underline that at the end of the day, this is only my opinion (so I encourage you to look at it in isolation, to break it down and only take those aspects from it that are constructive). If, for some reason, you find that something I have written was especially provoking to you or came across as a personal attack, then please PM me so that we can clear the air without derailing the thread.
While I am very much in favour of intellectual debate and open discussions (because speaking on topics freely is the mechanism by which we arrive at solutions to various problems), I doubt that inviting members of this "Pro-Life/Anti SaSui" group will produce anything of worth. I don't know how much can be gained when it seems that emotions are running high on both sides of the argument. @Jean4 herself has expressed her concern for the more vulnerable members of this forum and I would go as far as to say that by being actively suicidal, the majority of people here are vulnerable to some degree. This "side" is just as emotionally volatile as the other and the emotions of both parties are certain to colour perspectives in such a way that would make an "intellectual debate" near impossible.
I never cared for all of the argumentum ad hominem against so-called "pro lifers" and the family of Shawn Shatto in particular. Whether you agree with their actions or not, parents are not meant to bury their children and I cannot imagine the pain that this family must be feeling in the wake of their daughter's absence. I don't believe that censorship is the answer, but I would never go as far as to presume that they somehow "failed their child". If one insists that others ought to hold off on making baseless assumptions, then I should hope that the same courtesy is offered to someone else.
If @Jean4 feels that she is in the right frame of mind to discuss suicide with these people, then I would suggest that she invite them to talk personally through FB messages seeing as she already has their contact information on hand. In that way, the conversation would be private and set on a more level playing field (could you imagine coming over this this forum to debate believing that you are greatly outnumbered? It would be quite intimidating I think.).
Regarding the FB Group "Raid", I have to admit that I was a bit horrified when I saw it all going down. I didn't particularly agree with it and to be frank, its execution was sloppy and ended up doing more harm than anything else. The concerns raised by @HopeDiesLast were valid ones and even though some of you didn't like the delivery, I believe that they brought them with the intention of protecting those involved. I don't intend to blame the victim and no one should be made to feel threatened with the potential of being doxxed, but the fact is that others very well can and it is in one's best interest to take the proper precautions.
Asking for evidence is an acceptable practice in many scenarios and I do not think that anyone should take anything for face value without thinking about matters critically. My understanding was that these messages where delivered privately and are not searchable (through legitimate means anyway) by those on the outside, so asking someone to "look it up" is sort of a moot point unless you intend to allow them to access your account (and I certainly hope that no one does this). However, I also understand that in this situation, providing screenshots of conversations with the names redacted only serves to conceal the identities from those reading them here, the other party (if they are lurking) can easily determine the source of the "leak".
Honestly, I think that it would be best to drop it. To those directly involved, document everything on your end (just in case) and then block those group members. In the worst case scenario, you may want to consider deleting your compromised social media accounts...but for I realise that this isn't always possible (ex: personal business accounts etc).
Please be kind to one another and take good of yourselves.
