Anton, although I absolutely understand where you're coming from, I do believe people should be aware that shit like this is going on in their own neighborhoods. Animal cruelty is not only disgusting but it is also a very serious crime closely tied to other sociopathic tendencies. Often it is prelude to murder, torture, sexual assault and other extreme violence against people (see Macdonald Triad).
No one here is saying this is funny or the behavior in any way laudable. In fact, I'm certain many of us would like to beat the fuck out of those little bastards. D:<
As long as the video / thread provides adequate warning to potential viewers, I don't see any harm. Maybe that's just the tiny liberal (Kevin) inside of me?
