I thought about it, and I don't think I have any real questions, first I hope your are ok. But that isn't really a question. And secondly I was thinking about how a lot of questions I could ask feel more about me wanting to after a group I dislike than helping a victim out. Even a question like 'Did their internal processes give you support and some justice at least?' is answered by you coming here and offering this AMA.
So, the questions I more have is are you ok? And do you currently have a support network that is helping you out with things?
And for the rest I just think that if you feel like there are things you want to share you should share those (I think looking at your post you seem to want to talk about the harm reduction methods at those events, but not sure. Any important lessons we could take from that?) but don't want to pressure people into that, and also don't think I personally can totally do justice to the severity of situations like that. (which is of course on the problems with the discourse around SA).
