By that logic, doesn't someone also support "unhumane practices" if they do any kind of work or subcontract to US government? If you group everything together, then anyone supporting US is "directly responsible for an increase in human suffering". Does that really look like sound logic to you?
Of course not. I don't think there's anything in my comment that would suggest that.
My comment was explicitly about: inhumane acts done to apprehended migrants and building technology to apprehend more migrants. Those seem very connected.
Does the manufacturer of cars that they provide for the border patrol contribute to the "increase of suffering"? This technology is directly related to apprehending more migrants, in fact those cars are used on the ground to do that exact thing. Some of those cars are used to separate children from families by driving them away. To clarify, my point is if you see such technology as directly related, then cars would also be directly related?
