There’s been brigading from both sides, it’s just more noticeable when it’s an outcome you personally disagree with. I’m having to remind myself that just because a) my subreddit has someone who’s never posted there vehemently arguing to stay open and b) staying open is winning the poll, that doesn’t mean it’s a brigade.
(There would be more people voting if it was a brigade, so I’m pretty sure it’s not. But emotionally it bugs me.)
