You're missing the seventh group: trolls/assholes who will always press red but try to convince/muddy the waters about the blue button aiming to get a not-insignificant amount of <50% blue pushed to get people killed.

Prime candidate pool: 4chan.

If the question was restricted to local communities with 0 internet access, I would be more inclined to press blue.

But on a global scale? No fucking way.
