"Hold up. Why have I been put in this situation? Where's those responsible? Has anyone gone after the bridge guy, the brakes guy? Is anyone trying to get the sick fucks tying people down on tracks? What's being put in place to prevent this? Fences?Cameras? E-brakes? Who has liability and are they getting investigated?"
"Just Shutup and choose."
"I guess B is most logical."
"Oooh, you're a sick murderer and just want people dead!"
It's hard to participate when most people only have an A/B, us/them, left/right, right/wrong mentality view on things when it's obviously more complex when viewed from a few steps back. It's being stuck in either yard or on the fence, but if you climb a tree you'll realise there's many more yards and fences to the street to consider.
The issue, which is obvious to most people that aren't Euro-American, is that if you view generations of colonial violence as a normal baseline, then calling for "both sides" to "stop fighting" whenever colonial subjects resist isn't actually calling for peace. It's calling for the colonized to submit and go back to being quietly exterminated in an orderly fashion so you can go back to not thinking about it.
Which goes back to the saying "you can't use the masters tools to tear down the masters house." Which I disagree with, you can't use the masters tools to build your own house but you can and should use any and every tool available to you to tear down the masters house.
With that said, us being observers at best, you can just feel bad about the whole thing. It's okay to just feel bad that bad things are happening, you don't need to force that feeling to pick a side. There is no both sides argument, but people on both sides are getting hurt and it's okay to not feel okay about that.
No, but modern settler colonialism is largely limited to the Euro-American present. White Euro-Americans built the empire they now live in on a centuries long campaign of ongoing brutal extraction against the rest of the world, then turned around and said “This is just the way god made the world. Why would anyone want to disrupt this natural state of peace?”
There's no dilemma. If the goal is to express disapproval to people, then do what people think is disapproval... Which is doing nothing covered by some acting to appear as trying to do something
Do you even know what the rest of the people on the tracks will do if you stop the trolley? You will be responsible for what happens to the trolley operators and passengers.
