I dont know what criteria they are applying so I could, unfortunately, be a "general hater" (hope not but anyway). Do you think you could be a general hater? What's the use of information like this? Is it worthwhile gathering or does it just profile people who it'd be best not to make a subject of public attention?
Most of the time when I see people dressing up like riot police and storm troopers and carrying swastika flags I'm inclined to think, "Dude, its not halloween".
