As a mandated reporter and someone who deals with children affected by domestic violence on a somewhat regular basis, I would say there is a definite distinction. Not to take away from the disturbing images of police violence, protests, and general public mayhem, but what happens within a family unit behind closed doors is always going to hit a nerve with me.
Honestly though, I don't even think anyone posted the 9-minute clip of George Floyd dying in the political thread. We were able to to have a full conversation on the matter without the video, just like we are having a discussion on domestic violence right now. It isn't 4chan (or whatever is the current hub of gross videos) and we don't need to see every violent clip to have a reasonable discussion.
