Bonkers question. Can't even figure out living on Earth sustainably and you want to talk about doing it without gravity, an atmosphere or an ionosphere?
Not a bonkers question, it's actually totally predictable if you have an accurate read for both the White urge to despoil the frontier, and the depths of techbro narcissism. They just want to be the first to bust their load somewhere new, no matter what it takes, no matter whose resources they have to spend, no matter what they leave behind. Colonizer-assed cracker techbros always leave shit behind.
This is what the space-age (hwhite) colonizer's future looks like: every planet now has ring arrangements of dead satellites, empty fuel pods, blown-apart thrusters, and other assorted human-make space junk. Rings of garbage for all nine, dead vessels (crewed by now, long-dead, pressganged "conscripts" [because "conscript" causes less riots than "undesirable"]) hanging in high planetary orbits like macabre baby mobiles, and a still-smoldering coal where Earth used to be.
Don't you have natives of your own to be ceding your land back to, then going the fuck back to Britain afterwards? Settlers are settlers, no matter what white country they illegitimately live in. America, Britain, Australia, France, Spain, Belgium, the Nordics, all of you are exactly the same.
No you're just a settler brain dipshit that gets uncomfortable getting called out, the fact you are an Aussie calling someone else westerner is fucking rich lmao.
If they had said "actually I am from x" I could have engaged differently. But frankly it doesn't matter because they are getting very defensive and calling others westerners without even saying where they are from. They certainly don't have to I aint fishing for personal info or anything but given the surrounding context I could not help but respond the way I did.
