Okay. Someone 'splain to me how "alien" is racist?
For the same reason objecting to Islam is racist, when Muslims come in all races: because "racist" means whatever it serves the interests of The Party (the Democrat Party on this side of the Pond, the Labour Party, National Rally, SDU,... on the other), and accusing those who oppose your policies of being "racists" has proved very effective, since the English meaning of racist is now generally condemned.
Orwell correctly predicted the corruption of language in 1984, but got the method wrong. Real world Newspeak doesn't narrow the meaning of words so that only approved thought can be expressed, it makes the meaning of words diffuse so that unapproved thought can be more easily vilified.
