More generally, I have a thing for defending or amplifying voices that aren't being heard; whether it's because someone's just quiet by nature, because they're being brushed off, or because they're being drowned. Kind of like a 'look, shut the hell up for a second; there might be a point here' sort of thing. I could see that as wanting to establish some sort of 'social order.' The term sounds dirty and loaded with negative connotations () but I can roll with it.
I usually don't bother to voice my perspective if it's already been (or being) expressed by other people a million times. There's no value in doing so other than establishing solidarity; and well-represented groups don't really need that. One more chip added to the pile of a million is just a roundoff error. Not that I see expressing myself in those situations as a futile effort -- quite the opposite; I pretty much have been expressed, and also other people did the dirty work for me.
