Net als kosmonauten: ook zij zijn - ongeacht hun privégevoelens - vertegenwoordigers van 't genocidale Poetinregime. Daarom is het schandalig dat ESA, JAXA, CSA en NASA npg tot 2030 gewoon doorgaan met gezamelijk vliegen aan boord van het #ISS.
Fuck dat 'for all mankind' gelul om het goed te praten
