I would pick the blue button if children were included in the fray, otherwise going with red. There are an infinite number of reasons to pick the blue button, and simultaneously only two:
Reason A: You are retarded and don't understand basic logic.
Reason B: You are sympathetic to the Reason A retards and want to risk your life to save them. You are also, knowingly or not, banking on Reason C, D, and onward to bail you out.
Reason C: You are sympathetic to the Reason B people and want to risk your life to save them. You are also, knowingly or not, banking on Reason D, E, and onward to bail you out.
Reason D: You are sympathetic to the Reason C people and want to risk your life to save them. You are also, knowingly or not, banking on Reason E, F, and onward to bail you out.
Reason... (goes on to infinity)
The blue button campaign is a moral contagion that feeds on empathy, which is why it's effective on liberals. It also relies on the annihilation of human agency. The Reason B people don't respect the Reason A people's agency, otherwise they would permit them to annihilate themselves. To a certain extent, that's fine. What isn't fine are the Reason C and onward people, who perpetuate the contagion by throwing themselves into the grinder to save the Reason B people. Many of the Reason B people haven't thought that far ahead, but those who have are evil and should burn in hell for the lives they endangered to save morons.
