Different audiences have different opinions. Most of the places you would have seen the video were places where it was being upvoted and liked. So everyone was positive and those that weren't were downvoted and drowned out. This is something that isn't positive so all the negative opinions are here and positive opinions will probably be drowned out.
If the woman hadn't spoke up, how would anyone have known the truth of what happened /her side of the story / the the immorality of the video creator's actions?
