I see your argument that thinking how a pig in a meat factory feels is just speculation, but there is a point where we have to think about the future and speculate what could be and how possible it is. If we have better options now, and, maybe not as a single human, but collectively can act to stop this harm with a great possibility, I think it's worth it to speculate. I don't no where you draw this line, but it is beyond mine, so I am willing to speculate that this is the better way.
