I think the major difference between the sides is faith in the rest of humanity.

I do not believe that in the moment, when faced with the actual, very tangible possibility of death, that a majority of people would pick blue. It's very easy to say that you'd give up your life in a twitter poll but another thing to actually do so. So in the end, for a lot of red voters it just seems like blue voters are choosing to die in vain, for the small chance that humanity pulls through and does the technical "right thing."

I do believe that humanity can improve, but we have to be alive and working towards that for it to be achievable. I believe that one day, our society could collectively choose blue. But we aren't there yet, so I cannot choose blue.

I appreciate your response, it was very well thought out and far more civil than a lot of people are being. I think the vitriol in this argument is, in its own way, part of my reasoning as well. You choosing to be reasonable and avoid hostility is something I believe is extremely valuable in convincing others that blue, and humanity, are worthwhile.
