Which sounds more like he's talking about friends and associates telling him that Gamergating is not a good look.
Certainly we saw plenty of the latter type of reply when he posted on GAF about the issue. A lot of people suggested that he might not want to associate with the movement given how it started. I hope he didn't interpret those responses as a mafia-style "nice reputation you got here, would be a shame if anything happened to it." Because I don't think they were intended that way.
In any case, I'm sorry to hear that he's feeling threatened.
Yeah, I feel the same way - I really hope that no-one's actually threatened him. From the looks of that maybe it was just that he was feeling under pressure from a lot of people talking to him all at once. I contacted him a while back (not about his use of the GG hashtag because I didn't really want to get into that, but just to explain about CHSommers' views in particular), but then I ended up sending him another message after to give my sympathies to him when I saw what he'd posted about anxiety and depression, because it looked like he could do with some emotional support. It seemed like he was under a lot of stress, and I know how it feels to suffer from that; it's absolutely horrid.
(I'd personally rather the focus on Boogie stopped for basically that reason...taking him at his word about his anxiety, it looks like he's got too much of it to deal with, and I think that more focus on him could potentially just end up adding to it and creating more bad feeling, even if it's unintended.)
