I enjoy actual discussions, but in the OT threads that I see that are tied to identity politics, in my experience, tend to have a lot of folks using social justice as a cudgel for being an asshole and it being "OK". (The Trump thread where folks were justifying actual fucking terrorism because they were minorities might have done it for me).
So as one of the people posting in that thread, and as somebody who generally likes your posts but tends to find myself a little at odds with you on SJW threads/topics despite us apparently mostly agreeing, I thought I would respond to this.
I think this is an unfair reading of the conversation going on. I think those threads are mostly mostly about people's perspectives on societally accepted violence.
The concept of nonviolent civil disobedience rests on the assumption of a general societal agreement on the immorality of violence. The key idea is that your unwillingness to engage in violence, coupled with the violence of your enemies, will demonstrate the moral correctness of your position and create general support for your cause. In short, it assumes people will condemn the establishment for being unnecessarily violent towards you.
But if this weren't true, obviously, then nonviolent resistance is just suicide. If people generally agree that, if somebody is blocking the street, beating them or shooting them is fine and appropriate, then blocking the street would just result in injury or death on your part and no particular impetus to change for anybody.
Many people would argue, with some justice, that America is not a country with a general societal agreement on the immorality of violence when that violence is practiced on people of color. (Or on political outsiders in general -- see the Ludlow Massacre -- but especially today it has become more concentrated.) They would argue that the American society reserves the right to perpetrate terrible violence on people of color, not just for dissenting, but at any time and for no particular reason.
It doesn't seem unreasonable to suggest that if you lived in a society where there was no agreement by people not to commit violence against you, you would not feel responsible for avoiding violence against people who threatened you. That's just self-defense, right?
Now, I don't really think that people going to a Trump rally are threatening anybody, because, you know, he's a terrible candidate that will lose like 45 states. So, as I said, I wouldn't commit violence against them and I don't think it is appropriate to do so. But I can understand the thought process on the part of those who do, even though I disagree with it. A lot of people in those threads are happy to assert a position of complete nonviolence because they're very confident the violence their society threatens, and deploys, every day will never be turned against them. That is not a confidence everybody shares.
