The problem with situations like this is that race always gets brought up.
Muscle machine - whether or not the comparison to animals was justified is not the main issue. This was a despicable act and you should denounce it first.
By turning an act like this in to an issue of race always detracts from the real issue, which is that this was a violent act. If we lose sight of that then it will becomse a white vs black arguement which is stupid because i'm sure that all sensible people (balck and white) will denounce the actions on this video.
Secondly, a comment to everybody. Whilst this is a savage beating, you do not know the history of this clip. Taking this in isolation will not help anyone understand it. Who know what was said/done before the video started? Were these guys all gang-related or was the victim an innocent man? He also smashed the window of the X% which wasn't a smart move, and says to me that he may have antagonised the orignal situation.
When looking at clips like this, always think of what else might be going on.
Regardless, violence like this is wrong. But then this is the world we live in.
