I have friends who are social-justicey and I've read a lot online, and it continually feels like Social Justice is just an extended application of marxism. (I.e. there are some disadvantaged groups, and it's because the system, so take down the system by any means necessary!!) And Marxism itself suffers from being more of a critcism than offering an alternative moral system. http://slatestarcodex.com/2014/09/13/book-review-singer-on-m... I'm telling you so that you know that I've done the research.
And I hear you, I also get the feeling that mainstream political discourse is just different camps shouting out eachother's most obvious flaws. And our last election was a _perfect example of that_. When surveyed for why someone was going to vote Trump/Clinton, the most common answer was: "Well they're not Clinton/Trump!!". [citation needed]
But like, where do we go from there? We just can't talk to eachother because the other side is just trying to fuck with us? We gotta keep trying. Even if AlexRohde is not asking questions in good faith, you've got a chance to win over the audience.
