I've always had a problem with this argument, whether it was simply me not immersing myself in the politics surrounding it, or studying politics enough to understand the power structures that SJWs are speaking of. I do however understand democracy and how it operates in both America and Canada, but I still again have a hard time to comprehend the argument even with this knowledge. As far as I know, and correct me if I'm wrong, doesn't the power structure argue that all places of power are dominated by white men? That it is fundamentally pitted against minorities (even though in the US the majority of voters are women). As usual, this seems to be the argument the authoritarian liberals tend to cling to whenever they need a leg to stand on, I've encountered it a few times and usually found myself frustrated by the thought as it seems to always be used to support affirmative action which many of you should know is complete cancer.

So my question is, is there a proper way to address this argument? To the point where it is done and can't be regurgitated again? The second part being could someone also explain extensively. Whatever your arguments are against it then go for it, bring in political theory such as classical liberalism or whatever to back up your claims. Let's have a discussion.

TL;DR, What are "power structures" that SJW speak of and what are arguments against it.
