If I see concerning behavior, I feel the need to say something because it's concerning. More girls will be embarrassed, more people could be exploited, it's not ok. I feel like seeing that, knowing you can do something, and choosing not to is pretty close to condoning it. It's not about friend group politics; there are people outside the friend group who are being passed around in that without their knowledge or consent, and that's not ok. I wouldn't care if it was just guys with dark memes.
