Now, I don't know about you, but despite every horrible thing (some) people have ever done to me, I know that our species as a whole is still worthwhile, that as a whole we still deserve to live despite everything, and that given our current understanding of the climate situation stubbornly holding out on the Earth isn't the way to do that. If we don't go to space, all of humanity will die trapped on the Earth. Is that what you want?
You keep saying "we" as if you or your family is going there. You're not. Rich people are. The same rich people that fucked up this planet. They don't deserve to live if we're all gonna die. I'd rather drag them to hell with me. Fuck them.
