I get a weird spasm of pure rage when people compare climate change to nukes (not calling you out here, my issue is with people who attempt to minimize it with "I lived through the cold war and nuclear bomb drills" when dismissing climate angst) because the threat of nuclear war is inverted compared to climate change: nuclear war requires people to do it willfully. Climate change requires people to do nothing. We're already locked in. We are on the trajectory. If climate apocalypse can be compared to nuclear apocalypse then in this analogy the nukes are already in flight.
And to add even more to it: we still have nukes! We did not get rid of the nukes! You think a world with ecological and resource instability is going to be less inclined to use nukes than the half century of massive industrialization and economic growth after WW2? I would sleep better at night if I was that blessedly naive.
Oh and as for the "we did nuclear drills" shit... kids have school shooter drills. So just.. fuck those minimizers and their bullshit arguments. I hate them. So much.
Sorry for derailing in your Haiti thread but God almighty it strikes a chord in me when I see that kinda shit. So to bring it back to the original topic I believe these people absolutely will support walls and barb wire, auto turrets, guards with shoot-to-kill orders, the sinking of migrant boats with sea mines and naval weaponry. The whole arsenal will be deployed to ensure they are the last ones to feel the full weight of how much they fucked this planet up. And they will abdicate their responsibility while we all spiral into man-made hell and the 'christian missionaries' among them will solemnly hold out their palms in supplication and say "We're sorry, I guess it was God's will this happened."

And the fact that this person clearly thinks that they're smarter and superior to every Haitian when they don't even understand production. Racism is a disease, instead of trying to find the answer to this contradiction they conclude 'because they're African lol' they genuinely believe the 67 IQ lie.
