The sports hooliganism typically has a right wing bias..
I think you may have something in saying that. These mobs appear in large part to consist of drunken white dudes who have invested practically all of their emotional capacity for far too long into a meaningless, vicarious fiction. It's the sort of thing that ones relative privledge provides for, along with the accompanying amount of idle time on hand, in addition to a prior understanding that no great personal harm is likely to come of it, because authorities which largely consist of similar demographics to the rioters aren't likely to confront the hooliganism with guns blazing as they very well might in other circumstances. In this context we have violence and destruction being perpetuated as the result of a drunken lark with no particular focus or underlying message, no consideration of its consequences, informed by nothing other than a whim, or because they can in fact. It actually mirrors right wing violence in its content, at least for those who support it.
