You believe that calling attention to these people would be a good way to "target" them. -- Well, technically, that would be against Reddit rules (no DOXing) and in some ways would be illegal. We cannot promote people to go track down some jerk and deal with them.

The reality is, those types of posts and the individuals they attract only make it seem like a vocal minority is wrongfully a majority. They end up being the perfect staging grounds for the recruitment and empowerment of those groups.
